Comment 2 J Bachorik 2008-07-09 11:46:39 UTC

Reproduced. This seems like a problem with dangling invalid instrumentation code.
Assigning.

Comment 3 Tomas Hurka 2009-02-19 10:38:29 UTC

This is actually bug in JVM. Some methods don't get redefined when using jvmti->redefineClasses. Reported as CR 6805864.

Comment 4 Tomas Hurka 2009-04-15 11:56:28 UTC

This problem cannot be fixed in NetBeans Profiler.
