It's seems that the JBoss tools have problems to start JBoss 7.1.0- Beta 1. If I start the server i get an infinite error message after startup.
Error message is like that :
15:53:36,496 ERROR [org.jboss.remoting.remote] (Remoting "ws048059:MANAGEMENT" read-1) JBREM000200: Remote connection failed: java.io.IOException: JBREM000201: Received invalid message on Remoting connection 0161f888 to /127.0.0.1:2538
It's possible that the JBoss tools have a worng version of jboss-sasl-1.0.0.Beta6.jar ( that is the version of 7.1 Beta )
