I have investigated this deadlock problem but from the stack trace it appears
that one thread has traversed an impossible code path.  It is consistently
reproducible on one VM version, but not reproducible at all on any other
versions, so I suspect a VM or JIT bug.  Although I can easily recreate
the test scenario in a debugger, I cannot make it go down the invalid code
path.  I have made some minor changes in the code to try to "fool"
the compiler into not optimizing the snippet in question (I've made a field
accessed by two threads volatile to avoid thread local caching).  We'll
see if this does the trick for tomorrow's rebuild.

Also, since the deadlock occurred in label decoration, it's possible that
it was brought on by a bug that caused overly eager decoration (bug 39825).
 This bug has been fixed for tomorrow's build, so it might make the
problem go away.

I downloaded the build and test harness, and ran without any errors (see
attached result.xml). However the log you have provided shows a deadlock
between a "worker" thread the "main" thread.  

Could core please take a look at this to see if it may be a problem with
the job manager/decoration support. 

Thanks, 

Darin

I reran the Ant tests and encountered the same problem.  I have attached
the thread dump.
