This stack trace provided by Marko shows the problem: | at org.jboss.virtual.VFS.findChild(VFS.java:209) | at org.jboss.virtual.plugins.vfs.VirtualFileURLConnection.resolveVirtualFile(VirtualFileURLConnection.java:129) | at org.jboss.virtual.plugins.vfs.VirtualFileURLConnection.getVirtualFile(VirtualFileURLConnection.java:148) | - locked <0x32416218> (a org.jboss.virtual.plugins.vfs.VirtualFileURLConnection) | at org.jboss.virtual.plugins.vfs.VirtualFileURLConnection.getInputStream(VirtualFileURLConnection.java:99) | at java.net.URL.openStream(URL.java:1009) | at java.lang.ClassLoader.getResourceAsStream(ClassLoader.java:1161) | at javassist.LoaderClassPath.openClassfile(LoaderClassPath.java:70) | at javassist.ClassPoolTail.openClassfile(ClassPoolTail.java:335) | at javassist.ClassPool.openClassfile(ClassPool.java:594) | at javassist.CtClassType.getClassFile2(CtClassType.java:185) | at javassist.CtClassType.getAnnotations(CtClassType.java:453) | at javassist.CtClassType.getAvailableAnnotations(CtClassType.java:443) | at org.jboss.deployers.plugins.annotations.GenericAnnotationResourceVisitor.handleCtClass(GenericAnnotationResourceVisitor.java:173) | at org.jboss.deployers.plugins.annotations.GenericAnnotationResourceVisitor.handleCtClass(GenericAnnotationResourceVisitor.java:192) It's javassist that hits VFSURLConnection a lot, when trying to load annotations. I'll see if I can re-write this to use VFS directly. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4185352#...
