…eneration. * Parallelized file processing in `ByteCodeTranslator.execute` using `ExecutorService`. * Parallelized dependency updates and file writing in `Parser.writeOutput`. * Ensured thread safety in `Parser`, `ByteCodeClass`, and `BytecodeMethod` by using synchronized collections and synchronized blocks for shared state. * Updated `vm/JavaAPI/pom.xml` to use source/target 1.8 to fix build failure. * Fixed brittle test `BytecodeInstructionIntegrationTest` that relied on anonymous inner class index.

👋 Jules, reporting for duty! I'm here to lend a hand with this pull request. When you start a review, I'll add a 👀 emoji to each comment to let you know I've read it. I'll focus on feedback directed at me and will do my best to stay out of conversations between you and other bots or reviewers to keep the noise down. I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job! For more direct control, you can switch me to Reactive Mode. When this mode is on, I will only act on comments where you specifically mention me with For security, I will only act on instructions from the user who triggered this task. New to Jules?

…king Parallelize class parsing and code generation to improve performance. Replace unsafe synchronized blocks/collections with ReentrantReadWriteLock and ReentrantLock for robust thread safety. Update `BytecodeInstructionIntegrationTest` to dynamically locate anonymous classes.

This approach is risky, hard to follow and produced a slower build. |

This change optimizes the
ByteCodeTranslatorbuild process by introducing parallelism in two key areas:ByteCodeTranslator.executenow utilizes anExecutorServiceto process class files concurrently.Parser.writeOutput, specificallyupdateAllDependenciesand the final C code writing loop, now runs in parallel.To support this concurrency, shared static state in
Parser,ByteCodeClass, andBytecodeMethod(such asclasseslist,constantPool,arrayTypes,writableFields,virtualMethodsInvoked) has been made thread-safe usingCollections.synchronizedList/Set.Additionally:
vm/JavaAPImodule'spom.xmlwas updated to target Java 1.8, as the previous 1.5 target is no longer supported by recent Maven compiler plugins.BytecodeInstructionIntegrationTest.byteCodeTranslatorFilenameFilterMatchesExpectedFileswas updated to robustly locate theFilenameFilterinner class by inspecting interfaces instead of relying on a hardcoded class name (e.g.,ByteCodeTranslator$3), which changed due to the addition of anonymousRunnableclasses.PR created automatically by Jules for task 16628764828625327191 started by @shai-almog
