[jboss-remoting-issues] [JBoss JIRA] Closed: (JBREM-1073) Allow invocations to stopped servers to throw CannotConnectExceptions

Allow invocations to stopped servers to throw CannotConnectExceptions --------------------------------------------------------------------- Key: JBREM-1073 URL: https://jira.jboss.org/jira/browse/JBREM-1073 Project: JBoss Remoting Issue Type: Bug Security Level: Public(Everyone can see) Affects Versions: 2.2.2.SP10 Reporter: Ron Sigal Assignee: Ron Sigal Fix For: 2.2.2.SP11 org.jboss.remoting.transport.socket.SocketServerInvoker has a problem shutting down ServerThreads, which, for Remoting versions 2.4.0.GA and above, was fixed by the changes made for JBREM-821 "JBoss Remoting fails under load". However, the problem remains in Remoting versions 2.2.x. In particular, shutting down the SocketServerInvoker does not necessarily immediately close all if its ServerThreads. Consequently, on the client side, it is possible for an invocation to arrive and obtain a pooled connections to the closed SocketServerInvoker, which results in org.jboss.remoting.ServerInvoker, and therefore the call to org.jboss.remoting.Client.invoke(), throwing a ServerInvoker.InvalidStateException. This can cause problems for a clustered EJB3, leading org.jboss.invocation.unified.interfaces.UnifiedInvokerHAProxy to throw an UndeclaredThrowableException instead of trying an alternative server. One solution seems to be to allow, as an optional behavior, org.jboss.remoting.MicroRemoteClientInvoker to translate an InvalidStateException to an org.jboss.remoting.CannotConnectException.
