Re: [drlvm] If method throws exception after monitorenter, JIT does not release the lock

[Rana Dasgupta]

I am not sure if this is a problem. Would you expect the jit to generate the
finally code, reject the method, or what?

Hello, folks,

Could you, please clarify one issue.
The problem has described in JIRA
https://issues.apache.org/jira/browse/HARMONY-2504.

Thread makes monitorenter, and throws exception (NPE) to the output.
JASMIN code:
       .method public run()V
          .limit stack 3
          .limit locals 3

          getstatic Test/testField Ljava/lang/Object;
          monitorenter

          new java/lang/NullPointerException
          dup
          invokespecial java/lang/NullPointerException/<init>()V
          athrow

          getstatic Test/testField Ljava/lang/Object;
          monitorexit

          return
       .end method

Then other thread tries to get a lock. Deadlock occurs on Harmony.
Does this behavior is correct?

Thanks,
