Research direction

Start with the AtInvokeTest2 test and the TestAccessInterceptor.onInvoke entry point referenced in the trace. Reproduce the failure and inspect the bytecode around instruction 28, where the verifier reports that an object reference is missing. Done means AtInvokeTest2 executes without the IllegalArgumentException and the relevant test passes.
