@All, Matt Benson identified that the file *excluded.properties*, required for the TestPerClassLoaderRunner to function, isn't packaged in the test20.jar.
I verified his fix to the pom.xml file by copying the test cases we have for TestPerClassLoaderRunner from test12 to test20. (see the second attachment to the issue) As far as I can see, the test20 artifact is only used in the MyFaces Core ( https://svn.apache.org/repos/asf/myfaces/core/trunk) and it still builds with the changes. I also verified that the changes to the POM results in only one change to the jar, the addition of the excluded.properties file. The reason for this message is that changes to the POM file could have some unexpected results in other projects. So I would like to ask if someone else also can have a look at the proposed chnges and the possible impact. (so that I'm sure I didn't missed something) I'll commit the proposed patch by the end of the week if no one has any objections. Regards Rudy.
