bitronix.tm.resource.common.XAPool
Generic XA pool. {@link XAStatefulHolder} instances are created by the {@link XAPool} out of a{@link XAResourceProducer}. Those objects are then pooled and can be retrieved and/or recycled by the pool depending on the running XA transaction's and the {@link XAStatefulHolder}'s states. @author lorban
