Crash on older/low-end CPUs (EXCEPTION_ILLEGAL_INSTRUCTION in WinTray.dll due to AVX instructions)

[Wind092]

Hi,The application crashes immediately on startup when trying to initialize the system tray icon. The crash occurs in the com.kdroid.composetray native library (WinTray.dll). Reason for the crash:
The native library appears to be compiled with AVX (Advanced Vector Extensions) support. However, my processor (Intel Celeron G1820) physically lacks AVX support (Intel disabled AVX on Celeron/Pentium CPUs of that generation). As a result, the JVM encounters an EXCEPTION_ILLEGAL_INSTRUCTION (0xc000001d) at the specific AVX instruction vpxor xmm0, xmm0, xmm0 inside WinTray.dll and terminates. Environment details:App Version: 1.2.1 OS: Windows 11, 64 bit Build 22621 CPU: Intel(R) Celeron(R) CPU G1820 @ 2.70GHz (No AVX support) Runtime: OpenJDK Runtime Environment Microsoft-8905927 (21.0.2+13) Relevant part of the stack trace:PlaintextCurrent thread (0x00000235b6da8a50): JavaThread "WindowsTray-Thread" [_thread_in_native, id=5564, stack(0x00000035b8b00000,0x00000035b8c00000) (1024K)]

Suggested fix:Please consider recompiling WinTray.dll (or updating the com.kdroid.composetray dependency) with broader CPU architecture targets (e.g., standard SSE4.2 instead of AVX), or adding a fallback mechanism to disable the system tray if the native library fails to load.Thank you!

This may be a duplicate of kdroidFilter/ComposeNativeTray#401.

AVX2 compilation is configured in https://github.com/kdroidFilter/ComposeNativeTray/blob/973ab83f4c65ce34869139869ef3789b8399719d/src/native/windows/CMakeLists.txt#L20 so I think it would have to be fixed in that repository and the Microsoft distribution of OpenJDK can't do anything about it.

"Intel® Software Development Emulator (Intel® SDE)" would apparently be able to emulate AVX instructions on hardware that does not support them. But I don't know whether it is compatible with OpenJDK.

If the Compose Native Tray Library project is unwilling to change the AVX2 requirement, then you could also try asking the SimpMusic project to add a way to avoid Compose Native Tray entirely, perhaps by setting a system property. But the kdroidFilter/ComposeNativeTray#401 issue isn't even a day old yet so it seems too early for that.
