Hi, when starting JBoss Messaging in standalone mode, I found out that the JVM is not exited cleanly when we shutdown the server. After some investigation, I narrow the problem down to the JNDI server: | public static void main(String[] args) throws Exception | { | | System.setProperty("java.naming.factory.initial", "org.jnp.interfaces.NamingContextFactory"); | System.setProperty("java.naming.factory.url.pkgs", "org.jboss.naming:org.jnp.interfaces, value"); | | NamingBeanImpl namingInfo = new NamingBeanImpl(); | namingInfo.start(); | org.jnp.server.Main jndiServer = new org.jnp.server.Main(); | jndiServer.setNamingInfo(namingInfo); | jndiServer.setPort(1099); | jndiServer.setBindAddress("localhost"); | jndiServer.setRmiPort(1098); | jndiServer.setRmiBindAddress("localhost"); | jndiServer.start(); | | System.out.println("STARTED"); | | jndiServer.stop(); | namingInfo.stop(); | } | When I run the code (using both jnpserver 5.0.0.Beta3 and 5.0.0.Beta4), the VM hangs and I get the thread dump: | Full thread dump Java HotSpot(TM) Client VM (1.5.0_16-133 mixed mode, sharing): | | "DestroyJavaVM" prio=5 tid=0x010014b0 nid=0xb0801000 waiting on condition [0x00000000..0xb0800060] | | "NamingBootstrap Pool(1)-1" daemon prio=5 tid=0x01013480 nid=0x82be00 waiting on condition [0xb0e8e000..0xb0e8ed90] | at sun.misc.Unsafe.park(Native Method) | at java.util.concurrent.locks.LockSupport.park(LockSupport.java:118) | at java.util.concurrent.locks.AbstractQueuedSynchronizer$ConditionObject.await(AbstractQueuedSynchronizer.java:1841) | at java.util.concurrent.LinkedBlockingQueue.take(LinkedBlockingQueue.java:359) | at java.util.concurrent.ThreadPoolExecutor.getTask(ThreadPoolExecutor.java:470) | at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:674) | at java.lang.Thread.run(Thread.java:613) | | "GC Daemon" daemon prio=2 tid=0x010128e0 nid=0x914a00 in Object.wait() [0xb0e0d000..0xb0e0dd90] | at java.lang.Object.wait(Native Method) | - waiting on <0x25b02af8> (a sun.misc.GC$LatencyLock) | at sun.misc.GC$Daemon.run(GC.java:100) | - locked <0x25b02af8> (a sun.misc.GC$LatencyLock) | | "RMI Reaper" prio=5 tid=0x010124c0 nid=0x913c00 in Object.wait() [0xb0d8c000..0xb0d8cd90] | at java.lang.Object.wait(Native Method) | - waiting on <0x25b01b00> (a java.lang.ref.ReferenceQueue$Lock) | at java.lang.ref.ReferenceQueue.remove(ReferenceQueue.java:120) | - locked <0x25b01b00> (a java.lang.ref.ReferenceQueue$Lock) | at java.lang.ref.ReferenceQueue.remove(ReferenceQueue.java:136) | at sun.rmi.transport.ObjectTable$Reaper.run(ObjectTable.java:336) | at java.lang.Thread.run(Thread.java:613) | | "Timer-0" daemon prio=5 tid=0x010120c0 nid=0x84d200 in Object.wait() [0xb0d0b000..0xb0d0bd90] | at java.lang.Object.wait(Native Method) | - waiting on <0x25b01fa0> (a java.util.TaskQueue) | at java.lang.Object.wait(Object.java:474) | at java.util.TimerThread.mainLoop(Timer.java:483) | - locked <0x25b01fa0> (a java.util.TaskQueue) | at java.util.TimerThread.run(Timer.java:462) | | "RMI TCP Accept-1098" daemon prio=5 tid=0x01011d30 nid=0x84c400 runnable [0xb0c8a000..0xb0c8ad90] | at java.net.PlainSocketImpl.socketAccept(Native Method) | at java.net.PlainSocketImpl.accept(PlainSocketImpl.java:384) | - locked <0x25b01b58> (a java.net.SocksSocketImpl) | at java.net.ServerSocket.implAccept(ServerSocket.java:450) | at java.net.ServerSocket.accept(ServerSocket.java:421) | at sun.rmi.transport.tcp.TCPTransport.run(TCPTransport.java:340) | at java.lang.Thread.run(Thread.java:613) | | "Low Memory Detector" daemon prio=5 tid=0x01009110 nid=0x81ba00 runnable [0x00000000..0x00000000] | | "CompilerThread0" daemon prio=9 tid=0x01008660 nid=0x81ac00 waiting on condition [0x00000000..0xb0b077d8] | | "Signal Dispatcher" daemon prio=9 tid=0x01008130 nid=0x819e00 waiting on condition [0x00000000..0x00000000] | | "Finalizer" daemon prio=8 tid=0x01007a70 nid=0x818200 in Object.wait() [0xb0a05000..0xb0a05d90] | at java.lang.Object.wait(Native Method) | - waiting on <0x25a82180> (a java.lang.ref.ReferenceQueue$Lock) | at java.lang.ref.ReferenceQueue.remove(ReferenceQueue.java:120) | - locked <0x25a82180> (a java.lang.ref.ReferenceQueue$Lock) | at java.lang.ref.ReferenceQueue.remove(ReferenceQueue.java:136) | at java.lang.ref.Finalizer$FinalizerThread.run(Finalizer.java:159) | | "Reference Handler" daemon prio=10 tid=0x010076b0 nid=0x816a00 in Object.wait() [0xb0984000..0xb0984d90] | at java.lang.Object.wait(Native Method) | - waiting on <0x25a82208> (a java.lang.ref.Reference$Lock) | at java.lang.Object.wait(Object.java:474) | at java.lang.ref.Reference$ReferenceHandler.run(Reference.java:116) | - locked <0x25a82208> (a java.lang.ref.Reference$Lock) | | "VM Thread" prio=9 tid=0x01006e00 nid=0x815c00 runnable | | "VM Periodic Task Thread" prio=9 tid=0x01009c50 nid=0x806e00 waiting on condition | | "Exception Catcher Thread" prio=10 tid=0x010017b0 nid=0x80d800 runnable | Is it a known issue? Should I set some attributes on the JNDI server to ensure that it won't prevent the VM to exit? thanks! View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4222409#...
