[xwiki-users] Cannot undeploy in JBoss

Hi When I build the xwiki 1.1 branch myself, I cannot undeploy or shutdown JBoss normally anymore. This does noty happen if I use a binary download. Any idea what might be wrong? Thanks. 15:00:27,254 ERROR [STDERR] 03:00:27.254 WARN - Invalid feed URL: 15:00:41,878 INFO [Server] Runtime shutdown hook called, forceHalt: true 15:00:41,878 INFO [Server] JBoss SHUTDOWN: Undeploying all packages 15:00:41,878 INFO [TomcatDeployer] undeploy, ctxPath=/xwiki,warUrl=.../tmp/dep loy/tmp38404xwiki-web-standard-1.1-SNAPSHOT-exp.war/ 15:00:43,956 ERROR [STDERR] Exception in thread "AWT-Windows" 15:00:43,956 ERROR [STDERR] java.lang.IllegalStateException: Shutdown in progress 15:00:43,956 ERROR [STDERR] at java.lang.ApplicationShutdownHooks.add(ApplicationShutdownHooks.java:39) 15:00:43,956 ERROR [STDERR] at java.lang.Runtime.addShutdownHook(Runtime.java:192) 15:00:43,956 ERROR [STDERR] at sun.awt.windows.WToolkit.run(WToolkit.java:276) 15:00:43,956 ERROR [STDERR] at java.lang.Thread.run(Thread.java:619)
