["Alexey Varlamov (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/HARMONY-2504?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Alexey Varlamov updated HARMONY-2504:
-------------------------------------

             Component/s: Non-bug differences from RI
                Priority: Minor  (was: Major)
             Environment:     (was: Intel x86 IA32, WinXP)
    Estimated Complexity: Moderate
              Issue Type: Task  (was: Bug)
                 Summary: [drlvm] enforce structurted locking behaviour  (was: [drlvm] If method throws exception after monitorenter, JIT does not release the lock.)

Updated the issue accordingly to feedback from dev@.
This may be considered as RI compatibilty issue thus has lower priority. Possible ways to fix: 
- issue warnings during verification on Java code breaking structured locking;
- do post-mortem releasing of held monitors.

>  Thread makes monitorenter, and throws exception (NPE) to the output.
> java.lang.IllegalMonitorStateException expected to appear at the output
> (because, according to the specification, the last exception should appear).
> Then other thread tries to get a lock.
> DRLVM hangs up. It's throws NPE instead of IllegalMonitorStateException and does not release the
> lock.
