> There seems to be race condition between PoolFiller and CapacityFiller which results in wrong pool statistics
> I think what happens is:
>  - Both add connections to pool in different threads
>  - PoolFiller creates connection, then checks pools size and because pool has already certain size, it doesn't add connection and instead it destroys connection which increases destroyedCount
> see [SemaphoreConcurrentLinkedDequeManagedConnectionPool.java#L1163|https://github.com/ironjacamar/ironjacamar/blob/1.4/core/src/main/java/org/jboss/jca/core/connectionmanager/pool/mcp/SemaphoreConcurrentLinkedDequeManagedConnectionPool.java#L1163]
