JBoss Remoting logs at ERROR and WARN in many places ---------------------------------------------------- Key: JBREM-826 URL: http://jira.jboss.com/jira/browse/JBREM-826 Project: JBoss Remoting Issue Type: Bug Security Level: Public(Everyone can see) Reporter: Tim Fox Assigned To: Ron Sigal Fix For: 2.4.0.CR1 (Pinto) In many places JBoss Remoting logs at ERROR or WARN which seem inappropriate. JBR is a toolkit and should not log errors it does not handle. There is a general principle of you shouldn't log unless you handle the error. If you just pass it up, don't log. This principle is adhered to in JBoss AS for example, and IMHO should be used throughout all JBoss projects. If every toolkit being used in the chain logged the same error then you end up with a complete mess in the logs every time an exception occurs. Failover in JBoss Messaging is a good example. In JBM we detect failure of the remoting connection via the connection listener, and transparently reconnect on a different node. In this case, from the users POV *no error* has occurred - the process should be completely seamless. However JBoss Remoting spews a load of exceptions to the logs at ERROR and WARN, for example: SERVER 1 STDOUT: @RMI TCP Connection(2)-127.0.0.1 08:27:29,571 INFO [RMITestServer] kill() invoked - first deregistering from the rmi registry SERVER 1 STDOUT: @RMI TCP Connection(2)-127.0.0.1 08:27:29,572 INFO [RMITestServer] unregistered messaging_rmi_server_1 from registry SERVER 1 STDOUT: @RMI TCP Connection(2)-127.0.0.1 08:27:29,573 INFO [RMITestServer] unregistered naming_rmi_server_1 from registry SERVER 1 STDOUT: @RMI TCP Connection(2)-127.0.0.1 08:27:29,573 INFO [RMITestServer] Killing VM!!!! @main 08:27:29,940 INFO [ServerManagement] Waiting for server to die SERVER 0 STDOUT: @Timer-4 08:27:30,084 ERROR [SocketClientInvoker] Got marshalling exception, exiting SERVER 0 STDOUT: java.net.SocketException: end of file SERVER 0 STDOUT: at org.jboss.remoting.transport.socket.MicroSocketClientInvoker.transport(MicroSocketClientInvoker.java:577) SERVER 0 STDOUT: at org.jboss.remoting.transport.bisocket.BisocketClientInvoker.transport(BisocketClientInvoker.java:413) SERVER 0 STDOUT: at org.jboss.remoting.MicroRemoteClientInvoker.invoke(MicroRemoteClientInvoker.java:122) SERVER 0 STDOUT: at org.jboss.remoting.ConnectionValidator.doCheckConnection(ConnectionValidator.java:133) SERVER 0 STDOUT: at org.jboss.remoting.ConnectionValidator.run(ConnectionValidator.java:308) SERVER 0 STDOUT: at java.util.TimerThread.mainLoop(Timer.java:512) SERVER 0 STDOUT: at java.util.TimerThread.run(Timer.java:462) @main 08:27:30,241 INFO [ServerManagement] server 1 killed and dead @Timer-3 08:27:30,275 ERROR [SocketClientInvoker] Got marshalling exception, exiting java.net.SocketException: end of file at org.jboss.remoting.transport.socket.MicroSocketClientInvoker.transport(MicroSocketClientInvoker.java:577) at org.jboss.remoting.transport.bisocket.BisocketClientInvoker.transport(BisocketClientInvoker.java:413) at org.jboss.remoting.MicroRemoteClientInvoker.invoke(MicroRemoteClientInvoker.java:122) at org.jboss.remoting.ConnectionValidator.doCheckConnection(ConnectionValidator.java:133) at org.jboss.remoting.ConnectionValidator.run(ConnectionValidator.java:308) at java.util.TimerThread.mainLoop(Timer.java:512) at java.util.TimerThread.run(Timer.java:462) @Thread-9 08:27:30,318 WARN [Client] unable to remove remote callback handler: Can not get connection to server.

The customer says "Why was JBoss reporting errors when everything was ok?" If anything is to be logged in these cases it should be at DEBUG level at the highest, so it can be easily supressed in the standard log4j config. In the mean-time if you could provide a log4j config which supresses these messages for the specific classes so they don't appear even on ERROR level that would be much appreciated.
