------------------------------------------------------------------------------------------------------------------
Key: MYFACES-2878
URL: https://issues.apache.org/jira/browse/MYFACES-2878
Project: MyFaces Core
Issue Type: Bug
Affects Versions: 2.0.2-SNAPSHOT
Reporter: Werner Punz
In my local dialog test a sIEve showed 12000 delta nodes after 500 runs while Mojarras is on 5000, the goal of the fix is to get the deltas for the example down to zero and to reduce mem leaking to a big degree.
We have to fix this by the introduction of finalisation code in the affected classes on IE only!!!
The root cause of this is a non working garbage collection in IE because it relies on reference counting alone and refuses to persist on references into com objects.

Werner Punz resolved MYFACES-2878.
----------------------------------
Fix Version/s: 2.0.2-SNAPSHOT
Resolution: Fixed
Done, no sieve leaking anymore on my local test, the big + now is, my performance test outruns mojarra now by 30% on IE6. Mojarra is still leaking according to sIEve.
All the fixes however took their toll on the rest of the code. I lost 2 Seconds on my performance tests (used to be 14 now it is 16seconds) in firefox, which means I am again one sec slower than Mojarra on that browser.
In reality you probably wont notice.
