The ModuleNameDeployer created for the JBAS-7644 work attaches the metadata object that implements the NamedModule interface to the DU under key NamedModule.class. The naming deployers should get this attachment to find the module name, rather than using NamingJavaEEModuleInformer.getModulePath().

Note that my JBAS-7644 work actually hacked NamingJavaEEModuleInformer.getModulePath() to have it get the NamedModule attachment rather than returning a path. That was to allow the deployer to get integrated and tested in hudson pending completion of this subtask.
