Error description

  • Error Message: An object may become locked by a thread that no
longer exists causing other threads to hang by waiting for the
object to become unlocked.
.
Stack Trace: N/A
.
This issue is only present if the deprecated method
Thread.stop() is used.

Local fix

  • -Xjit:disableRedundantAsyncCheckRemoval

Problem summary

  • In JIT compiled code, there are certain code regions that were
not capable of unlocking objects held by the thread destroyed by
the Thread.stop() method.

Problem conclusion

  • This defect will be fixed in:
5.0.0 SR13
6.0.0 SR10
6.0.1 SR1
.
The JVM was modified to prevent throwing the exception from
async check points in the jit, and only throws from the method
enter check.
.
To obtain the fix:
Install build 20110502 or later
