Either way, it's obvious that ExportedClassFolderReferenceResolver should at least guard against the possibility of a null reference url. I'm committing a simple guard check. The logic here is that if the url is null, it cannot possibly be an ExportedClassFolderReferenceResolver reference, since all such references have a url beginning with module:/org.jboss.ide.eclipse.as.wtp.core.vcf.exportedClassFolders A null reference url cannot be an ExportedClassFolderReferenceResolver. The null check will ensure this method returns false. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/645861#645861] Start a new discussion in JBoss Tools at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
