JBoss EAP 6.0.1 (JBoss AS 7.1.3.Final-redhat-4) doesn't seem to work correctly on Eclipse 4.2/JBoss Tools 4.
The server starts and stops correctly, but the "JBoss Enterprise Application Platform 6.x Runtime" node under "Java Resources" -> src -> Libraries in e.g. a Dynamic Web Project is empty. None of the types that the runtime normally puts on the classpath are available.
Upon inspecting, it seems that between EAP 6.0.0 (JBoss AS 7.1.2.Final-redhat-1) and JBoss EAP 6.0.1 (JBoss AS 7.1.3.Final-redhat-4), jboss-eap-6.0/modules/javax/activation/api/main/activation-1.1.1-redhat-1.jar has been renamed to jboss-eap-6.0/modules/javax/activation/api/main/activation-1.1.1-redhat-2.jar, but the runtime somewhere references the -1.jar version.
After some more fiddling, I got Eclipse to emit the following build path error:
The container 'JBoss Enterprise Application Platform 6.x Runtime [JBoss EAP 6.0 Runtime]' references non existing library '/Users/henk/eclipse42/jboss-eap-6.0/modules/javax/activation/api/main/activation-1.1.1-redhat-1.jar'
