[jira] Commented: (HARMONY-2905) [drlvm][jvmti]
java.lang.VerifyError is thrown for instrumented class
[ https://issues.apache.org/jira/browse/HARMONY-2905?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12463543 ]
Ivan Popov commented on HARMONY-2905:
-------------------------------------
This looks like a problem with incorrect instrumentation used in TPTP profiler engine.
I've submitted bug against TPTP profiler: http://issues.apache.org/jira/browse/HARMONY-2905
Will check if this problem goes away after this bug is fixed.

> Key: HARMONY-2905
> URL: https://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

> 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.
