Hi,
I get this exception if I put CheckClassAdapter in the visitors chain before ClassWriter. The code I use is below:
ClassReader reader = new ClassReader(classfileBuffer);
ClassWriter writer = new ClassWriter(reader, ClassWriter.COMPUTE_MAXS);
BasicClassAdapter adapter = new BasicClassAdapter(new CheckClassAdapter(writer), className, classBeingRedefined);
reader.accept(adapter, ClassReader.SKIP_DEBUG);
By running this I get error with details:
java.lang.IllegalStateException: Try catch blocks must be visited before their labels
at org.objectweb.asm.util.CheckMethodAdapter.visitTryCatchBlock(CheckMethodAdapter.java:679)
at org.objectweb.asm.MethodAdapter.visitTryCatchBlock(MethodAdapter.java:170)
at test.agent.instrumentation.BasicMethodAdapter.visitMaxs(BasicMethodAdapter.java:86)
However my instrumentation code work perfectly well if run this without CheckClassAdapter. Not sure what I'm missing here.
I tried this when seeing the mail from Eugene to use CheckClassAdapter to catch various issues.
My BasicClassAdapter is the implementation of FinallyAdapter from asm-transformations.pdf
Can somebody help me out here?
Regards,
Rajaraman
