[jira] Commented: (HARMONY-1582) [drlvm] Implementation of Invocation API for DRLVM

    [ http://issues.apache.org/jira/browse/HARMONY-1582?page=comments#action_12440183 ] 
            
Geir Magnusson Jr commented on HARMONY-1582:
--------------------------------------------

patch doesn't quite apply... it can't find vm_shutdown.cpp in vmcore/src/init/ - was that from a JIRA that wasn't listed as a pre-req?

> Hi,
> I've finished implementation of Invocation API for DRLVM. Eclipse runs OK. Smoke and kernel tests passes on Windows and Linux (with some exceptions of course :-)). I have some expected failures and some new one in kernel test java.lang.Thread on Windows and java.lang.ThreadGroup on Linux. Actually these tests worked fine before this Monday (09/25). I think the last patch  for condition vars (HARMONY-1519?) introduced these failures. Also I had to switch cunit tests off because of linking problems. Hopefully original authors of cunit tests can fix the problem in the right way.
> One more workaround is disabling warnings on Linux. We need to find a way to get rid of "warning: invalid access to non-static data member `JavaVM_Internal::link' of NULL object". It happenes because of APR_OFFSETOF. I believe we can resolve this together.
> There are two restrictions in the current implementation:
> 1) Only on VM can be created in the process address space. Actualy it's not a problem of Invocation API implementation rather than VM design itself. Additional work required to have this feature.
> 2) DestroyJavaVM doesn't clean its internals properly. It kills the process instead. It is not a trivial task to implement it properly. I suggest do it separetly (not in this patch).
> So waiting for your comments......and quick integration :-)
> Thanks
