Strange message after invoking management query

javahamburg Aug 15, 2012 8:51 AM

Hi,

I query the management queue, but after invokation I get the following message on the server side (the client-side closes without exceptions):

[Old I/O server worker (parentId: 1985191693, [id: 0x76539f0d, localhost/127.0.0.1:5445])] 14:14:16,787 SEVERE [org.hornetq.core.server.impl.ServerSessionImpl]  Failed to remove temporary queue jms.queue.hornetq.management.c86d2cef-5a2c-44a7-abaa-2bd9a7e839a4

This is basically the code used:

ClientRequestor requestor = new ClientRequestor(getSession(), "jms.queue.hornetq.management");
ClientMessage message = getSession().createMessage(false);
ManagementHelper.putAttribute(message, ResourceNames.CORE_SERVER, "addressNames");
ClientMessage reply = requestor.request(message);
Object[] arrayObjects = (Object[])ManagementHelper.getResult(reply);

When I try to use the requestor.close() method, I get a NPE on the serverside.

Any Ideas? Thanks

Daniel

Here is the full stacktrace on the server, only happens when calling close(), otherwise only the mentioned "Failed to remove temporary queue" log message is printed:

Thanks, I'll wait for 2.3.0, since I'm really interessted in the replication feature.
Updating the poms from 2.0.0 to 2.2.5 was a pain, and there seems not to be any official documentation for this - so I just want to delay this pain.
