Support for invokedynamic (Java 8 Lambdas) in ByteCodeTranslator #4279
Conversation
…s and method references. - Implemented `visitInvokeDynamicInsn` in `Parser.java` to translate lambda expressions and method references into static proxy classes. - Updated `vm/JavaAPI/pom.xml` to use source/target 1.8 to support newer build environments and lambdas. - Added `LambdaIntegrationTest.java` in `vm/tests` to verify end-to-end compilation and execution of Java 8 lambda code translated to C. - Handled generation of necessary stubs (`java.lang.invoke`, `java.util.Objects`) in integration tests.

👋 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.
