Strange message after invoking management query

[javahamburg]

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

what's the stacktrace of the NPE on the server?

[javahamburg]

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:

Any idea?

[jbertram]

What version of HornetQ are you using?

[javahamburg]

2.2.5.Final on Linux 64bit. JDK 1.6u33

[clebert.suconic]

this was fixed on later versions:

https://github.com/hornetq/hornetq/commit/852f1b41da6a63a9b8f56f36c5151a500bf61bc3

[clebert.suconic]

you should move to a later release. 2.2.5 is fairly old now

[javahamburg]

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.
