+# Proposal to Break org.jnode.vm.core ↔ rt Circular Dependency
+
+**Date:** 2025-11-16  
+**Status:** Proposal for Discussion
+
+## Executive Summary
+
+This document proposes a concrete approach to break the circular dependency between `org.jnode.vm.core` and `rt` plugins, involving 154 classes. The proposal focuses on the most practical and least risky approach: **moving specific classes between plugins and extracting API interfaces**.
+
+## Background
+
+Based on the detailed analysis in `VM_CORE_RT_CYCLE_DETAILED_ANALYSIS.md`:
+- **113 classes** in org.jnode.vm.core import from rt
+- **41 classes** in rt import from org.jnode.vm.core
+- Most dependencies involve fundamental JVM classes (java.lang.*, java.util.*, etc.)
+
+## Analysis of the Problem
+
+### Root Cause
+
+The circular dependency exists because:
+
+1. **Native VM implementations in rt** need access to JNode-specific VM classes (VmType, VmSystem, VmIsolate, etc.)
+2. **VM core classes** use standard Java APIs from rt (Collections, I/O, Security, etc.)
+3. **javax.isolate API** (in rt) wraps JNode VM implementations
+
+### Why This is Difficult
+
+The dependency is **fundamental to the architecture**:
+- The VM needs the standard library to operate
+- The standard library needs VM internals for native implementations
+- This is a classic bootstrap problem
+
+## Recommended Approach
+
+Given the analysis, I recommend **Strategy 1 with targeted moves** as the most practical solution:
+
+### Phase 1: Move JNodePermission to rt (EASY - Quick Win)
+
+**Rationale:**
+- JNodePermission is a simple security permission class
+- It only extends java.security.BasicPermission (already in rt)
+- It's used by both rt and vm.core
+- Moving it eliminates one circular dependency
+
+**Changes:**
+1. Move `core/src/core/org/jnode/permission/JNodePermission.java` → `core/src/classpath/vm/org/jnode/permission/JNodePermission.java`
+2. Update `rt` plugin descriptor to export `org.jnode.permission.*`
+3. Remove `org.jnode.permission` export from `org.jnode.vm.core` descriptor
+4. Update any imports in both plugins
+
+**Impact:** Minimal - simple class with no dependencies on vm.core internals
+
+**Risk:** Low - it's already a shared API-like class
+
+### Phase 2: Create org.jnode.vm.isolate.api Plugin (MEDIUM)
+
+**Rationale:**
+- The javax.isolate API (in rt) currently wraps VmIsolate classes (in vm.core)
+- This creates a tight circular dependency
+- Extracting isolate APIs breaks this cycle
+
+**Changes:**
+
+1. **Create new plugin:** `org.jnode.vm.isolate.api`
+   
+2. **Move isolate API interfaces:**
+   - Create interface versions of: VmIsolate, VmLink, VmStreamBindings, LinkMessageFactory
+   - Keep implementations in org.jnode.vm.core with interface implementations
+   
+3. **Update dependencies:**
+   ```
+   rt → org.jnode.vm.isolate.api (for javax.isolate wrapper implementations)
+   org.jnode.vm.core → org.jnode.vm.isolate.api (implements the interfaces)
+   org.jnode.vm.isolate.api → rt (uses java.* classes)
+   ```
+
+4. **Affected classes in rt (4 classes):**
+   - javax.isolate.LinkMessage
+   - javax.isolate.Isolate  
+   - javax.isolate.StreamBindings
+   - javax.isolate.Link
+
+5. **Affected classes in vm.core (7 classes):**
+   - org.jnode.vm.isolate.VmIsolate
+   - org.jnode.vm.isolate.VmLink
+   - org.jnode.vm.isolate.VmStreamBindings
+   - org.jnode.vm.isolate.LinkMessageFactory
+   - (plus related implementation classes)
+
+**Impact:** Medium - requires interface extraction and implementation updates
+
+**Risk:** Medium - affects isolate subsystem but well-isolated
+
+### Phase 3: Analyze Native Implementation Pattern (COMPLEX - Later)
+
+**Observation:**
+Most rt → vm.core dependencies are in "Native*" classes:
+- NativeObject, NativeSystem, NativeRuntime, NativeThread, etc.
+- These are JNode's implementations of standard Java native methods
+
+**Two Options:**
+
+**Option A: Keep as-is (RECOMMENDED)**
+- Accept that Native* implementations need VM access
+- Document this as a design decision
+- The circular dependency at this level is **by design** - the VM and runtime are tightly coupled
+
+**Option B: Move Native* classes to vm.core**
+- Move all Native* implementations from rt to org.jnode.vm.core
+- Update rt descriptors to keep only pure Java classpath code
+- **Risk:** High - breaks the separation between classpath and VM
+
+**Recommendation:** Keep Native* classes in rt but accept the dependency as **intentional and necessary**. The VM and its native implementations are inherently coupled.
+
+## Detailed Implementation Plan
+
+### Step 1: JNodePermission Move (1-2 hours)
+
+```bash
+# 1. Move the file
+mkdir -p core/src/classpath/vm/org/jnode/permission
+git mv core/src/core/org/jnode/permission/JNodePermission.java \
+       core/src/classpath/vm/org/jnode/permission/JNodePermission.java
+
+# 2. Update rt descriptor (core/descriptors/org.classpath.core.xml)
+# Add to <export> section:
+#   <export name="org.jnode.permission.*"/>
+
+# 3. Update vm.core descriptor (core/descriptors/org.jnode.vm.core.xml)
+# Remove from <export> section:
+#   <export name="org.jnode.permission.*"/>
+
+# 4. Build and test
+./build.sh clean build
+```
+
+### Step 2: Create org.jnode.vm.isolate.api (4-8 hours)
+
+```bash
+# 1. Create descriptor: core/descriptors/org.jnode.vm.isolate.api.xml
+# 2. Create interface directory structure
+# 3. Extract interfaces from implementation classes
+# 4. Update implementations to implement interfaces
+# 5. Update javax.isolate classes to use interfaces
+# 6. Build and test extensively
+```
+
+### Step 3: Document Decision (1 hour)
+
+Create architectural documentation explaining:
+- Why Native* → vm.core dependency is acceptable
+- The bootstrap architecture
+- Guidelines for future development
+
+## Expected Outcomes
+
+After implementing Phases 1 and 2:
+
+### Reduction in Circular Dependencies
+- **Before:** 154 classes involved in cycle
+- **After Phase 1:** 153 classes (-1)
+- **After Phase 2:** ~145 classes (-9)
+- **Remaining:** ~145 classes (mostly Native* implementations)
+
+### Improved Architecture
+- Clear API layer for isolate subsystem
+- Better separation between public APIs and implementations
+- Documented and accepted VM/runtime coupling
+
+### Remaining Circular Dependencies
+**Accepted as intentional:**
+- Native* implementations need VM internals ✓ By design
+- VM needs Java standard library ✓ Fundamental requirement
+
+## Why Not Other Strategies?
+
+### Why not Strategy 4 (Merge vm.core and rt)?
+**Answer:** Would lose modularity and make the codebase harder to maintain. The separation between VM implementation and standard library is valuable.
+
+### Why not move all Native* classes?
+**Answer:** Native* classes implement the Java standard library's native methods. Moving them to vm.core would break the conceptual separation between "standard library" and "VM implementation."
+
+### Why not create interfaces for everything?
+**Answer:** Overhead and complexity. Most VM ↔ rt dependencies are fundamental and cannot be broken without major architectural changes.
+
+## Risk Assessment
+
+| Phase | Risk Level | Mitigation |
+|-------|-----------|------------|
+| Phase 1: JNodePermission | **LOW** | Simple move, well-isolated class |
+| Phase 2: Isolate API | **MEDIUM** | Extensive testing, incremental rollout |
+| Remaining dependencies | **LOW** | Accept as design decision, document |
+
+## Testing Plan
+
+For each phase:
+
+1. **Unit Tests:** Verify moved/changed classes work correctly
+2. **Integration Tests:** Test isolate functionality end-to-end  
+3. **Build Tests:** Ensure clean build with no circular plugin dependencies
+4. **Boot Tests:** Verify JNode boots correctly with qemu
+5. **Regression Tests:** Run existing test suites
+
+## Timeline
+
+- **Phase 1:** 1 day (implementation + testing)
+- **Phase 2:** 3-5 days (implementation + extensive testing)
+- **Documentation:** 1 day
+- **Total:** 5-7 days of focused development
+
+## Alternatives Considered
+
+1. **Do Nothing:** Not acceptable - circular dependencies cause build and maintenance issues
+2. **Major Refactoring:** Too risky - would destabilize the entire VM
+3. **Consolidation:** Loses architectural benefits of separation
+
+## Conclusion
+
+This proposal offers a **pragmatic, incremental approach** to breaking the circular dependency:
+
+✅ **Quick wins** with minimal risk (Phase 1)  
+✅ **Targeted improvement** where it matters (Phase 2)  
+✅ **Accepts reality** for fundamental VM/runtime coupling  
+✅ **Documents decisions** for future maintainers  
+
+The key insight: **Not all circular dependencies should be eliminated**. Some represent fundamental architectural relationships that are better accepted and documented than fought against.
+
+## Recommendation
+
+**Proceed with Phase 1 immediately** as a low-risk quick win, then evaluate Phase 2 based on team feedback and priorities.
+
+---
+
+**Next Action:** Review this proposal with the development team and get approval to proceed with Phase 1.

+# Circular Dependency Analysis - README
+
+This directory contains a comprehensive analysis of the circular dependency between the `org.jnode.vm.core` and `rt` plugins in the JNode project.
+
+## Problem Statement
+
+The task was to:
+1. Read documentation in `docs/plugins`
+2. List detailed source-level dependencies between `org.jnode.vm.core` and `rt`
+3. Sort results by classes with fewer dependencies (involved in circular dependency)
+4. Propose solutions to break the circular dependency
+
+## Delivered Artifacts
+
+### 1. Analysis Tool: `analyze_vm_core_rt_cycle.py`
+
+**Purpose:** Automated tool to analyze the circular dependency between org.jnode.vm.core and rt at the Java source code level.
+
+**Usage:**
+```bash
+python3 analyze_vm_core_rt_cycle.py
+```
+
+**Output:**
+- Generates `VM_CORE_RT_CYCLE_DETAILED_ANALYSIS.md` with complete dependency list
+- Shows all 154 classes involved in the circular dependency
+- Lists classes sorted by number of dependencies (least dependencies first)
+- Separates vm.core → rt dependencies from rt → vm.core dependencies
+
+**What it does:**
+- Parses plugin descriptors to identify which packages belong to which plugins
+- Analyzes Java import statements in all source files
+- Maps dependencies at the class level
+- Generates detailed reports with actionable recommendations
+
+### 2. Detailed Analysis Report: `VM_CORE_RT_CYCLE_DETAILED_ANALYSIS.md`
+
+**Content:**
+- **154 classes** involved in the circular dependency
+- **113 classes** in org.jnode.vm.core that import from rt
+- **41 classes** in rt that import from org.jnode.vm.core
+- Each class listed with:
+  - Full qualified class name

+
+## Key Findings
+
+### Statistics
+
+| Metric | Value |
+|--------|-------|
+| Total classes in cycle | 154 |

+| Native* implementation classes | 31 |
+| javax.isolate wrapper classes | 4 |
+| Classes with 1 dependency | 33 |
+| Classes with 2-5 dependencies | 61 |
+| Classes with >5 dependencies | 60 |
+
+### Top Refactoring Candidates
+
+**From org.jnode.vm.core (classes with 1 dependency):**
+1. `VmSystemSettings` - imports java.util.Properties
+2. `JNodePermission` - imports java.security.BasicPermission ⭐ **Phase 1 target**
+3. `BaseVmArchitecture` - imports java.nio.ByteOrder
+4. `VmReflection` - imports java.lang.reflect.InvocationTargetException
+5. `ResourceManagerImpl` - imports javax.naming.NamingException
+
+**From rt (classes with 1 dependency):**
+1. `javax.isolate.LinkMessage` - imports org.jnode.vm.isolate.LinkMessageFactory ⭐ **Phase 2 target**
+2. `javax.isolate.Isolate` - imports org.jnode.vm.isolate.VmIsolate ⭐ **Phase 2 target**

+5. `java.lang.VMSecurityManager` - imports org.jnode.vm.VmSystem
+
+### Architecture Insight
+
+The analysis reveals an important architectural pattern:
+
+**Native* Classes Pattern:**
+- 31 out of 41 classes in rt that depend on vm.core are "Native*" implementation classes
+- These classes implement JNode's native method implementations
+- Examples: NativeObject, NativeSystem, NativeThread, NativeRuntime, NativeUnsafe
+- This dependency is **by design** and represents the fundamental coupling between:
+  - The Java standard library (rt)
+  - The VM implementation (vm.core)
+
+**Conclusion:** This is not a bug - it's the bootstrap architecture. Accept and document it.
+
+## Recommended Actions
+
+### Immediate (Low Risk)
+✅ **Phase 1: Move JNodePermission**
+- Move from org.jnode.vm.core to rt
+- Reduces circular dependency by 1 class
+- Very low risk - simple permission class
+- Estimated time: 1 day including testing
+
+### Short Term (Medium Risk)
+⏭️ **Phase 2: Extract Isolate API**
+- Create org.jnode.vm.isolate.api plugin
+- Move isolate interface definitions
+- Reduces circular dependency by ~9 classes
+- Medium risk - requires interface extraction
+- Estimated time: 3-5 days including testing
+
+### Long Term (Documentation)
+📝 **Phase 3: Document Native* Pattern**
+- Document the Native* → vm.core pattern as intentional
+- Create architectural guidelines
+- Accept ~145 remaining dependencies as fundamental
+- Estimated time: 1 day
+

+
+## Notes
+
+### Why Not Eliminate All Dependencies?
+
+The analysis shows that full elimination of the circular dependency is:
+1. **Not necessary** - Some coupling is by design
+2. **Not beneficial** - Would require major architectural changes
+3. **Not practical** - Native implementations fundamentally need VM access
+
+### Focus Areas
+
+Instead of trying to eliminate all dependencies, focus on:
+1. ✅ Reducing **accidental** coupling (Phases 1 & 2)
+2. ✅ Documenting **intentional** coupling (Phase 3)
+3. ✅ Maintaining clear architectural boundaries
+4. ✅ Tracking dependencies over time

+# Summary: Analysis of org.jnode.vm.core ↔ rt Circular Dependency
+
+**Date:** 2025-11-16  
+**Task:** Analyze and propose solutions for breaking the circular dependency between org.jnode.vm.core and rt plugins
+
+## Deliverables
+
+This analysis provides three key documents:

+
+### 2. Concrete Implementation Proposal
+**File:** `BREAKING_VM_CORE_RT_CYCLE_PROPOSAL.md`
+
+**Content:**
+- Three-phase approach to reducing the circular dependency

+```
+
+## Key Findings
+
+### Classes with Least Dependencies (Best Candidates for Refactoring)
+
+**From org.jnode.vm.core → rt (top 5):**
+1. `VmSystemSettings` - 1 dependency
+2. `JNodePermission` - 1 dependency ⭐ Recommended for Phase 1
+3. `BaseVmArchitecture` - 1 dependency
+4. `VmReflection` - 1 dependency
+5. `ResourceManagerImpl` - 1 dependency
+
+**From rt → org.jnode.vm.core (top 5):**
+1. `javax.isolate.LinkMessage` - 1 dependency ⭐ Part of Phase 2
+2. `javax.isolate.Isolate` - 1 dependency ⭐ Part of Phase 2
+3. `javax.isolate.StreamBindings` - 1 dependency ⭐ Part of Phase 2
+4. `javax.isolate.Link` - 1 dependency ⭐ Part of Phase 2
+5. `java.lang.VMSecurityManager` - 1 dependency
+
+### The Native* Pattern
+
+**Finding:** 31 out of 41 classes in rt that depend on vm.core are "Native*" classes:
+- NativeObject, NativeSystem, NativeThread, NativeRuntime, etc.
+- These implement JNode's native method implementations
+- This dependency is **by design** and should be accepted
+
+### Recommended Actions
+
+**Immediate (Low Risk):**
+- Move `JNodePermission` from vm.core to rt
+- Impact: Reduces circular dependency by 1 class
+- Risk: Very low - simple permission class
+- Time: 1 day including testing
+
+**Short Term (Medium Risk):**
+- Create `org.jnode.vm.isolate.api` plugin with interfaces
+- Move isolate API definitions out of implementations
+- Impact: Reduces circular dependency by ~9 classes
+- Risk: Medium - requires interface extraction
+- Time: 3-5 days including testing
+
+**Long Term (Documentation):**
+- Document the Native* → vm.core pattern as intentional
+- Create architectural guidelines for future development
+- Accept ~145 remaining dependencies as fundamental to the design
+- Time: 1 day
+
+## Architecture Insight
+
+The analysis reveals a fundamental truth about JNode's architecture:
+
+> **The VM and runtime are intentionally coupled.** The Java standard library (rt) contains native method implementations that must access VM internals. The VM uses standard Java classes. This is not a bug - it's the bootstrap architecture.
+
+**What this means:**
+- Full elimination of the cycle is neither necessary nor desirable
+- Focus should be on reducing **accidental** coupling
+- **Intentional** coupling (Native* implementations) should be documented and accepted
+

+| javax.isolate wrapper classes | 4 |
+| Classes with 1 dependency | 33 |

+## Recommendations to Break the Circular Dependency
+
+### Strategy 1: Extract Common API Interfaces
+
+Create a new plugin `org.jnode.vm.api` that contains only interfaces:
+
+1. **Identify common interfaces** used by both vm.core and rt
+2. **Move interfaces** to the new API plugin
+3. **Update dependencies:**
+   - Both `org.jnode.vm.core` and `rt` depend on `org.jnode.vm.api`
+   - Remove direct dependencies between vm.core and rt
+
+### Strategy 2: Move Classes with Fewest Dependencies
+
+Start with classes that have the least dependencies (listed above):
+
+**From org.jnode.vm.core to rt (or new plugin):**
+- `org.jnode.vm.VmSystemSettings` (1 dependency/dependencies)
+- `org.jnode.vm.VmReflection` (1 dependency/dependencies)
+- `org.jnode.vm.ResourceManagerImpl` (1 dependency/dependencies)
+- `org.jnode.vm.VmProcessClassLoader` (1 dependency/dependencies)
+- `org.jnode.vm.performance.PerformanceCounters` (1 dependency/dependencies)
+
+**From rt to org.jnode.vm.core (or new plugin):**
+- `javax.isolate.LinkMessage` (1 dependency/dependencies)
+- `javax.isolate.Isolate` (1 dependency/dependencies)
+- `javax.isolate.StreamBindings` (1 dependency/dependencies)
+- `javax.isolate.Link` (1 dependency/dependencies)
+- `java.lang.ThreadHelper` (1 dependency/dependencies)
+
+### Strategy 3: Dependency Inversion
+
+Apply the Dependency Inversion Principle:
+
+1. **Define interfaces** for high-level dependencies
+2. **Inject implementations** at runtime
+3. **Use service locators** or dependency injection
+
+### Strategy 4: Consolidate Plugins
+
+If separation is not critical:
+
+1. **Merge vm.core and rt** into a single plugin
+2. **Document the merger** in plugin documentation
+3. **Update all plugin descriptors** that reference these plugins
+
+### Priority Actions
+
+Based on the analysis, prioritize:
+
+1. **Quick wins:** Classes with 1-2 dependencies
+2. **Medium effort:** Classes with 3-5 dependencies
+3. **Major refactoring:** Classes with >5 dependencies
+
+## Next Steps
+
+1. Review this detailed analysis with the development team
+2. Choose a strategy based on project constraints and goals
+3. Create a plan for incremental refactoring
+4. Test each change thoroughly to ensure system stability
+5. Document the architectural decisions
