Yes there are tests and they are working.
But they obviously don't have enough code coverage
(unless you include this test :-), see below.

You bring this up on the very day that Ales releases 2.0.0.GA of jboss-cl. ;-)

The issue is the parent policy we are using for the
java2ClassLoadingCompliance=false

  |    public ParentPolicy getDeterminedParentPolicy()
  |    {
  |       if (isJ2seClassLoadingCompliance())
  |          return ParentPolicy.BEFORE;
  |       else
  |          return ParentPolicy.AFTER_BUT_JAVA_BEFORE;
  |    }
  | 

The AFTER_BUT_JAVA_BEFORE actually means
java.* and javax.* is delegated to the parent before asking the web-app

http://viewvc.jboss.org/cgi-bin/viewvc.cgi/jbossas/projects/jboss-cl/branches/Branch_2_0/classloader/src/main/java/org/jboss/classloader/plugins/filter/JavaOnlyClassFilter.java?revision=78356&view=markup

Wheras previously in jboss-4.2 it was just java.* that got delegated to the
parent before asking the web-app.

So this is a bug.
