Memory Leak After Upgrading AMQ

Solution Verified - Updated -

Issue

After upgrading our AMQ 7 brokers to AMQ 7.8.3, we are seeing what looks like a memory leak. Looking into the heap dump of the broker, we see several large ServerSessionImpl objects, each occupying several hundred megabytes. Looking further, each of these contains a large hashmap of ProtonAbstractReceiver objects. Is this an actual memory leak?
