ActiveMQ resource adapter on EAP: poor throughput and many threads blocking on ResponseCorrelator operations
Issue
An application runs on EAP (6.x, 7.x) and communicates with an ActiveMQ message broker using the resource adapter. Messages are consumed as part of an XA transaction. Under load, throughput is poorer than expected, and JVM stack dumps reveal large numbers of threads blocking on ResponseCorrelator operations.
Environment
