Thanks for the suggestions guys. Josh was right in that what I was seeing was not a problem, just what I thought was a problem. I reduced my heap from about 1.5GB down to 512MB and saw GC happening as expected and no OOMEs with a moderate consistent load on the app. I think I got the idea that it needed a lot of headroom from the dev environment, where production mode was disabled, and live class reloading uses up a lot of space (I think), otherwise the process was crashing with heap issues. Thiago, your suggestion of using VisualVM was very helpful - a very good tool. It looks like Tapestry (at least 5.2.1) is very good at releasing resources - my heap size vs. used heap is consistently bouncing between predictable levels even after running tests 24 hours over a few days. Very happy with the result. Summary, the creep was me misinterpreting the heap growing because I gave it so much headroom it never really needed to GC.
