@AndyTaylor: Can you take a look on this:

There's a simple Unit test that I wrote on my branch for now... clebertsuconic/master

Look at org.hornetq.tests.unit.core.postoffice.impl.WildcardAddressManagerUnitTest

That's basically what's happening under the hood at the integration test that is also replicating this issue:

org.hornetq.tests.integration.jms.client.testShouldNotThrowException

Both tests are replicating this really easily. From what I can see the removeTopic is removing the dependency from the WildCard what will break it on the second step.. And after that it's impossible to add any more queues to the wildcard.

Also: notice that I'm placing the Bindings interface back that was removed on master.

Just as a note to someone else wanting to look into my branch:

git remote add clebert git://github.com/clebertsuconic/hornetq.git

git fetch clebert -fp

git checkout clebert/master -b master-clebert
