Tibor Digana commented on SUREFIRE-1132:
----------------------------------------
I was fixing MavenProject.class in https://github.com/apache/maven/pull/34
We agreed with Jason to wait for immutable objects in maven-core, and not to
push my temporary fix for MavenProject.class.
In case of MavenProject#getArtifacts(), that's Maven Core code. If you are sure
about that, then the bug should belong to https://jira.codehaus.org/browse/MNG
Optionally you may watch the discussions in maven mailinglist
http://maven.40175.n5.nabble.com/Maven-Developers-f142166.html
and two discussions related in the sense of concurrency issues
http://maven.40175.n5.nabble.com/Formal-verification-of-thread-correctness-in-maven-core-td5822508.html
http://maven.40175.n5.nabble.com/GitHub-maven-pull-request-Improved-visibility-of-collections-and-variabl-td5821775.html
That's maximum I can help now.
Cheers

> 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
