Release is part of the endpoint handler interface and is supposed to
be called by the resource adapter directly. I think the problem is
we are simply opening too many concurrent MdbConnections. For each
MDB in the itest app (7) we allow up to 10 instances to be created.
In the setMessageDrivenContext of these beans, we create a MdbInvoker
which opens an ActiveMQ connection, and looking at the service-
jar.xml file, we have a connection limit of 30 connections.
We may be able to make this problem go away by changing the
MdbInvoker code to open and then close a connection each time it
needs one in a try/finally block.
Do you want to give this a shot?

Hi,
I am sometimes getting a ResourceException when I run the tests
as shown below.
javax.resource.ResourceException: No ManagedConnections available
within configured blocking timeout ( 5000 [ms] ) for pool

@1ad552c.
Once this error comes all the remaining tests fail with the same
error. I am wondering if this is because connections are not properly
released from the pool after use
I was debugging trying to figure why this occurs and found that the
release() method on the EndpointHandler class is never getting called.
Thus ejbRemove methods are never called(or so i think :)).

Some insights from the MDB guy will be appreciated :)
