Re: Intermittent failure of org.apache.qpid.test.unit.basic.PropertyValueTest

Tue, 06 Mar 2007 14:59:55 -0800

I have seen this a couple of times as well. It occurs when the message reference count goes negative.. which clearly shouldn't happen. Guess there is a issue some where with the reference counting.

I'm also seeing this failure intermittently. Is someone looking into it? A quick search didn't turn up a JIRA for it. I get the following output 
at the end of mvn test and then it just hangs:
