Subject [jira] Commented: (HARMONY-1383) [util.concurrent] Some LockSupport unit tests fail after TM integration
Date Sun, 08 Oct 2006 19:12:21 GMT
    [ http://issues.apache.org/jira/browse/HARMONY-1383?page=comments#action_12440777 ] 
Rustem Rafikov commented on HARMONY-1383:

By the way, 
the patch for 1567 adds LockSupport back to the DRLVM kernel classes. Let's it be duplication
for a while, till agreements on VMI classes for Object/Thread manipulation be made. So, 1.
we get juc working with DRLVM, 2. we don't need make changes to DRLVM right how especially
if these have to be redone later.

Is it ok?

> Hi All, 
> Preparing a patch for juc integration I found some regressions after integration of ThreadManager.
> I used a DL's unit tests and the attached tests were extracted from them.
> To reproduce:
> 1. Put LockSupport.java (attached) in vm/vmcore/src/kernel_classes/javasrc/java/util/concurrent/locks/
> 2. build DRLVM (or kernel classes)
> 3. comment "concurrent.jar" in lib/bootclasspath.properties
> 4. Compile and run the tests attached.
> - TestParkUntil - hangs (looks like it does not calculate deadline)
> - TestIntAfterPark - shows that "interrupted" flag is not set after interruption of a
parked thread.
