New ClassLoader not finding generated classes in the bootstrap classloader
--------------------------------------------------------------------------

                 Key: JBCL-17
                 URL: http://jira.jboss.com/jira/browse/JBCL-17
             Project: JBoss ClassLoader
          Issue Type: Bug
          Components: ClassLoader
    Affects Versions: JBossCL.2.0.0.Beta12
            Reporter: Adrian Brock
         Assigned To: Adrian Brock
             Fix For: JBossCL.2.0.0.CR1

An optimisation in the new classloader is causing a backwards compatibility problem.

When we load classes from the parent (bootstrap) classloader,
we first check to see whether we can getResource() on the class file.

This avoids excessive locking when many threads are trying to loadClass() on that classloader.

However, if the class is a runtime generated class against that classloader getResource()
will return null, leading to a ClassNotFoundException.

While we've always done this optimization for JBoss ClassLoaders, it looks like we can't to do
this non-jboss classloaders and maintain backwards compatibility.
