• Create a new class able to handle a pool of TreeSitter wasm module: TreeSitterPool

For pooling we successfully followed this pattern in the past:
https://github.com/StyraOSS/opa-java-wasm/blob/main/core/src/main/java/com/styra/opa/wasm/OpaPolicyPool.java

Did you checked that it's effective and the increase of complexity(and infrastructure) is really saving time at the end?

The most important thing that I would like to achieve here is to be able to have x instances where an instance can handle a tree-sitter grammar/language to parse files (= and to populate ASTree) and to allow to query AST trees using S-expression queries

As a the beginning of the process, the tool using this lib will load from a path (= java application) collections of file where a collection corresponds to a language: java, properties, etc then the idea is to allow to parallel the work to build the AST trees for the different languages in parallel

what you are asking is achievable also without pooling, let see what the bottleneck really is and fix it

So this is here that we should have a look to parallelize the process reading the files and building the ASTrees for each language: https://github.com/ch007m/java-tree-sitter/blob/5dfe908a8ad4eeed75f1d885ca441f207bf20fa1/tree-sitter4j-client/src/main/java/dev/snowdrop/treesitter4j/util/ASTParserUtil.java#L134-L172
