What is special about wars for the aspect deployer? I'm still trying to understand how the JBossWebMetaData is coming into the picture and causing problems now, but not before the war class loader change. Note that you can ask about whether an attachment is present using its name as DeploymentUnit.isAttachmentPresent(Class type) is just a convenience method for isAttachmentPresent(type.getName()).

I will try looking for that info in the in ClassLoadingMetaData of the war's sub deployment. Ok, this may not be in synch with the new org.jboss.deployers.structure.spi.classloading.ClassLoaderMetaData attachment. I'll have to check that. What is the code your working on here so I can understand what type of class loader processing your doing?
