I think there is a small problem in the code of the org.jboss.console.remote.InvokerServlet In the processRequest() method, it has this in case an error occurs: catch(Throwable t) | { | t = org.jboss.mx.util.JMXExceptionDecoder.decode (t); | org.jboss.invocation.InvocationException appException = new org.jboss.invocation.InvocationException (t); | log.debug ("Invoke threw exception", t); | // Marshall the exception | response.resetBuffer (); | org.jboss.invocation.MarshalledValue mv = new org.jboss.invocation.MarshalledValue (appException); | javax.servlet.ServletOutputStream sos = response.getOutputStream (); | java.io.ObjectOutputStream oos = new java.io.ObjectOutputStream (sos); | oos.writeObject (mv); | oos.close (); | } It should probably surround the block of code after the comment "Marshal the exception" with a try catch on IllegalStateException, just in case the response cannot be sent back (for example, if the requester is disconnected).
