[Java] Deadlock running Java tests
Anyone seen this deadlock (running
org.apache.qpid.systest.rest.BasicAuthRestTest) before?
It's in a checkout where I've been making changes, but none that I
think would affect this code:

Re: [Java] Deadlock running Java tests
Posted by Oleksandr Rudyy <or...@gmail.com>.
Hi Rob,
I was able to reproduce the issue with JDK 1.7.0_14 when running
BasicAuthRestTest in a cycle. However, I was not able to reproduce it
with JDK 1.6.0_33 by running the same tests during a period of 2 days.
I raised a JIRA QPID-4660 for the issue.
Kind Regards,
Alex

Running jdk1.7.0_06.
I've not seen it before either, and have not been able to reproduce.
None of my local changes touch the areas being exercised, so I don't
think it was down to them. Curious.

Re: [Java] Deadlock running Java tests
Posted by Oleksandr Rudyy <or...@gmail.com>.
Hi Rob,
I have not seen this issue.
Also, I tried to reproduce the issue by running the BasicAuthRestTest
in a cycle but could not reproduce it during 1 hour of running. I
continue running the test.
Could you please clarify what is the version of JVM you are using?
