The way this works is broken. It choose the first classloader in a HLR as the classloader for the ScopedClassLoaderDomain. But if that classloader is redeployed it still uses the old classloader (or not since it gced :-) I've hacked it so there is now a Domain.isValid() which checks to see whether the classloader is still useable. This fixes the tests. But this HACK is also broken. A HLR can have multiple classloaders and we don't want to throw away a scoped domain just because one of the classloaders is redeployed. So the fix only works for the simple usecase where a HLR has one classloader. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4065958#...
