> Project: Maven Surefire
> Issue Type: Bug
> Affects Versions: 2.6
> Environment: Maven 2.2.1, 3.0RC1
> Reporter: Stephen Coy
> Priority: Critical
> Attachments: surefire dump.png
>
>
> We have a module containing over 500 unit tests, most of which create
> Hibernate sessions with a largish data model.
> Surefire 2.6 fails to complete these tests, even with:
> <jvmArg>-Xmx512m</jvmArg>
> specified.
> Surefire 2.5 (and earlier) completes these tests with no trouble at all,
> without jvmArg settings.
> I performed a heapdump (which is too big to upload here) and it shows that
> org.apache.maven.surefire.util.TeeStream seems to be hanging on to data in
> memory. The 20 biggest objects by retained size were all instances of this.
> I've attached a screen dump
