AjaxSelfUpdatingTimerBehavior memory?
I have a question on the AjaxSelfUpdatingTimerBehavior
I have some memory issues and wondered in the behavior could cause this (on Jetty)
When connected with jvisualvm I see the heap increasing each time the AjaxSelfUpdatingTimerBehavior is fired (with about 3M per request)
Is that what I should see?
?Thx
-Rob

It looks OK.
The memory grows but after (manual) GC it is freed.

I have reproduced it in a quickstart.

Note that I am running in debug mode; but that should not matter I suppose.

Hi,
Definitely not!
Capture some memory snapshots and see what is the difference between them.
I'm not sure whether VisualVM can do that but Eclipse MAT can.
