Hi, I notice Apache Artemis still uses ParallelGC by default. Did anyone try Java 17 or 18 with ZGC already?
We're using a symmetric cluster setup. Our nodes have 4 CPU's and 24GB memory. With ParallelGC we're experiencing long stop the world pauses every few weeks, resulting in an instable cluster (because of unnecessary failovers/failbacks or even crashes). The situation improved with G1GC, except for major garbage collections. ZGC looks promising with really short pauses, but I'm uncertain whether this is tested and production ready with Artemis 2.26.0? P.S. We're experiencing some strange behaviors with this setup. The cluster is working well, but suddenly redistribution seems to fail on one of the nodes resulting in missing messages. More on this in a separate issue...
