Ensure that the header value for priority is read and returned in a form
that is scaled such that it won't cause an IndexOutOfBoundsException
from the QueueImpl priority array. Adds some additional testing for
message priority support.
When a replica attempts to connect to a live server using a group-name
and there are > 1 servers on the network using that group there is a
chance it will fail because it doesn't keep track of all of the
topology data it receives. This fix ensures that all the topology data
from the cluster tracked until it is used and fails at which point it
is discarded.
This is moving the smoke tests creates as part of the relication tests.
They are also now based on junit tests.
And to support starting servers I am exposing basedir to unit tests in general.
When populate-validated-user = true AMQP messages can cause exceptions.
This feature isn't particularly applicable to AMQP so this commit
eliminates the exception and leaves the AMQP messages untouched
even if populate-validated-user = true. In other words,
populate-validated-user + AMQP is not supported.
This is now considering only threads waiting for the queue to get new tasks as idle.
The thread pool maintained a counter of active threads, but that counter was increased
too late in the beforeExecute method. Submitting a task created a new thread.
If now a second task was submitter before the new thread had started to execute it's task,
the second task was queued without creating a 2nd thread. So the second task was only
executed after the first task had been completed - even if the thread pool's
maximum number of thread had not been reached.
This fix now maintains the delta between the number those threads that are currently waiting
in the queue's poll or take methods as idle threads, and the number of queued tasks.
It creates new threads unless there are enough idle threads to pick up all queued tasks.
This closes#1144
