memory leak skinfactories hold on to skin which holds on to stylesheetnodes
---------------------------------------------------------------------------
Key: TRINIDAD-2087
URL: https://issues.apache.org/jira/browse/TRINIDAD-2087
Project: MyFaces Trinidad
Issue Type: Improvement
Components: Skinning
Reporter: Jeanne Waldman
related to TRINIDAD-2026.
SkinFactory#_FACTORIES is holding on to StyleSheetNodes. We register all
skins with the SkinFactory. Once a skin has been requested by the user, we
parse the stylesheet and store the stylesheetnodes with the skin.
To see in the memory profiler tool, first set the LRUCache for
SkinStyleProvider to 1. This will only keep
around one SkinStyleProvider at a time. Run the rich client app (or
trinidad's panelPageSkinDemo). Change the skin to about 6 different skins.
Stop the memory profiler. You will see that even though we limit the
SkinStyleProvider to 1, we still see StyleSheetNodes growing.
See attached image showing the profiler results.
Think about using SoftReferences to the Skin
