Andreas Gudian commented on SUREFIRE-1132:
------------------------------------------
Ah, the last info is very interesting. I've seen that one before as well, in a
parallel build with compile, not test-compile, and with JDK 1.6.0_45. We had
that one solved by updating to the lastest JDK 8 version to perform the
compilations. We just discarded it as a JDK bug (worked fine with 1.6.0_26).
But it is a strong hint that these issues are indeed closely related and that
it's not Surefire.
Nevertheless, forkCount=1 could help you out there.
> Surefire: regular isolated classloader failures in parallelbuild

> Key: SUREFIRE-1132
> URL: https://jira.codehaus.org/browse/SUREFIRE-1132
> Project: Maven Surefire
> Issue Type: Bug
> Components: classloading
> Affects Versions: 2.17
> Environment: SLES 3.0.80-0.7-default SMP x86_64 GNU/Linux
> windows server 2008 x64
> Maven 3.2.2, 3.2.3, 3.2.5
> Oracle HotSpot JDK 7u25

> We have a large project of 300+ modules which regularly fails with different
> kind of classloading issues in different places in surefire plugin. The issue
> is reproduced only with parallel build and is not reproduced in single
> threaded. This is a main contributor in build instability for us. All the not
> loaded dependnecies are actually present in dependency tree. I attached 3
> different samples of how build fails.
> Surefire config:
> {code}
> <configuration>
> <forkCount>0</forkCount>
> <!--doesnt work in parrallel build. Causes build
> failures with error java.io.IOException: Stream Closed-->
> <redirectTestOutputToFile>false</redirectTestOutputToFile>
> <useManifestOnlyJar>false</useManifestOnlyJar>
> </configuration>
> {code}
> maven cmd is like install -T 10
> Please advise how to sort this out - ready to run any provided diagnostic
> and evaluate any options.
> Thanks in advance, Alexander
