Subject NPE when closing
Date Fri, 28 Apr 2006 21:10:13 GMT
I'm running a broker embedded in a tomcat server.  I'm getting a NullPointerException when
the server is shut down.
The exception stack trace is:
        at org.apache.activemq.ActiveMQConnection.syncSendPacket(ActiveMQConnect
        at org.apache.activemq.ActiveMQConnection.close(
The transport class is org.apache.activemq.transport.vm.VMTransportServer$1  It looks like
the VM transport server never responds to the request to shutdown.  The call to Transport.request
times out and returns null.
Has anyone seen this problem before?  Is it a problem with the way i'm setting up the VM transport?

My transport configuration is:
       <transportConnector name="default" uri="vm://localhost" />
       <transportConnector name="external" uri="tcp://localhost:61616" />
Thanks for any help you can provide.
