[jboss-dev-forums] [Design of JBoss Remoting, Unified Invokers] - Ability to restart a Connect with SocketServerInvoker

I'm seeing some issues with an AS clustering test that attempts to restart (ie. deploy, then stop(), then start()) a bunch of services. They tie back to restarting an instance of UnifiedInvoker and how it interacts the Remoting classes. Problem occurs when trying to start a UnifiedInvoker that has previously been deployed: | 2008-06-04 12:33:00,382 DEBUG [org.jboss.invocation.unified.server.UnifiedInvokerHA] (RMI TCP Connection(31)-127.0.0.1) Starting failed jboss:service=invoker,type=unifiedha,partitionName=RestartPartition | java.lang.IllegalArgumentException: Illegal cache capacities | at org.jboss.util.LRUCachePolicy.<init>(LRUCachePolicy.java:77) | at org.jboss.remoting.transport.socket.LRUPool.<init>(LRUPool.java:44) | at org.jboss.remoting.transport.socket.SocketServerInvoker.start(SocketServerInvoker.java:231) | at org.jboss.invocation.unified.server.UnifiedInvoker.startService(UnifiedInvoker.java:140) | at org.jboss.system.ServiceMBeanSupport.jbossInternalStart(ServiceMBeanSupport.java:376) | at org.jboss.system.ServiceMBeanSupport.jbossInternalLifecycle(ServiceMBeanSupport.java:322) | at sun.reflect.GeneratedMethodAccessor65.invoke(Unknown Source) | at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) | at java.lang.reflect.Method.invoke(Method.java:585) Looking into this I've found a couple things: 1) The UnifiedInvoker stopService() method has this: | public void stopService() throws Exception | { | if(serverInvoker != null) | { | serverInvoker.stop(); | } | } That seems broken. The UnifiedInvoker is handed back a ref to the serverInvoker when it registers itself with the connector as a ServerInvocationHandler. AFAICT, that serverInvoker belongs to the Connector, and any other registered handlers will also have a ref to it. So UnifiedInvoker should not be stopping it; the stop of one handler shouldn't affect the other handlers. 2) Seems SocketServerInvoker can't be restarted. If you call stop(), it calls cleanup(), which does this: maxPoolSize = 0; // so ServerThreads don't reinsert themselves Thereafter, if you call start(), the max pool size will be less than the min pool size, leading to the exception shown above.
