[drlvm][jvmti] java.lang.VerifyError is thrown for instrumented class
---------------------------------------------------------------------

                 Key: HARMONY-2905
                 URL: http://issues.apache.org/jira/browse/HARMONY-2905
             Project: Harmony
          Issue Type: Bug
          Components: DRLVM
         Environment: Windows/ia32, Linux/ia32
            Reporter: Ivan Popov


DRLVM (r) cannot execute HelloWorld class instrumented by Eclipse TPTP profiler either statically
or dynamically. The following exception is thrown:

2. run instrumented class
Uncaught exception in main:
java.lang.VerifyError: (class: mytests/HelloWorld, method: <init>()V) Uninitialized
reference usage

FAILED to invoke JVM.

To reproduce this error get test attached to HARMONY-2200 and run it against DRLVM build.
Only case 1 with original not instrumented class is finished successfully. In all three other
cases, where instrumented class is executed, VerifyError is thrown. RI works fine with this
instrumented class.
