Re: [infinispan-dev] Tests failing: ports shared across modules

Hello, Looking into hudson's tests on http://hudson.jboss.org/hudson/view/Infinispan/job/Infinispan-trunk-JDK6-tcp it appears the number of failed tests change from build to build even by documentation changes or other unrelated changes. Two examples: Build #1031 : Changes: Typos in javadocs Test Result (4 failures / -1) a javadoc change fixed a test? Build #1033 : Changes: [ISPN-301] (Closing the Lucene Directory will close the cache too) Test Result (8 failures / +2) So while I only changed something related to Lucene, the failures in core increased? In some of the test errors you can find evidence of communication between test scenarios, like these: http://hudson.jboss.org/hudson/view/Infinispan/job/Infinispan-trunk-JDK6-... http://hudson.jboss.org/hudson/view/Infinispan/job/Infinispan-trunk-JDK6-... first one from the Lucene module, second from the Tree module: they both have the node vmg22.mw.lab.eng.bos.redhat.com-42912 and are complaining about an unexpected number of participants. Looking into the other errors it always looks like as "someone else" changed the cache, but there's no evidence, so I think we should solve the isolation problem first? Both stacktraces show that they're using org.infinispan.test.MultipleCacheManagersTest.createClusteredCaches(MultipleCacheManagersTest.java:137) to setup the caches, so it doesn't appear to be a problem with these two testcases. This kind of interactions don't seem to happen inside a single module, could it be a classloader problem? A static threadlocal defines the jgroups port to use, but it's "static" in a per-module world, instead of globally static? I've added some logging to org.infinispan.test.fwk.JGroupsConfigBuilder, 2 snippets of the result: [org.infinispan.test.fwk.JGroupsConfigBuilder] (pool-1-thread-1) TCP bind_port:7900 ClassLoder:org.apache.maven.surefire.booter.IsolatedClassLoader@2e93d13f [...many lines..] [org.infinispan.test.fwk.JGroupsConfigBuilder] (pool-1509-thread-10) TCP bind_port:7900 ClassLoder:org.apache.maven.surefire.booter.IsolatedClassLoader@2d1a2259 I see the two classloaders being different, and while the threads are different they are sharing the same bind_port 7900.

Looking into http://maven.apache.org/plugins/maven-surefire-plugin/examples/class-load... It looks like from Surefire 2.4.3 the default is to use a shared system classloader, but there's a little warning at the bottom of page about not being possible to not isolate the classloader while using forkMode=none ideas? P.S. where can I get the sources of maven-surefire-plugin version2.4.3-JBOSS ?
