Summary: Memory leak in ViewScopeBeanHolder
Key: MYFACES-3924
URL: https://issues.apache.org/jira/browse/MYFACES-3924
Project: MyFaces Core
Issue Type: Bug
Affects Versions: 2.2.4
Environment: Wildfly 8.1.0.Final
Reporter: Dan Østerberg
When running som stress tests, we noticed a severe memory leak, which causes
our server to crash witin a few minutes when under pressure. It works fine on
Mojarra (2.2.8). Our views aren't particularly big, but we do attach some JPA
entities to our ViewScoped beans and we thus need them to be cleaned up in
reasonable time.
The views are destroyed properly, but field "storageMap" in
org.apache.myfaces.cdi.view.ViewScopeBeanHolder holds onto the references,
preventing view state & beans from being GCed.
To us, the problem seems to be as easy as that method
ViewScopeBeanHolder.destroyBeans(String) doesn't remove the destroyed
ViewScopeContextualStorage from the map. Simply replacing the initial
"storageMap.get(viewScopeId)" with "storageMap.remove(viewScopeId)" in that
method solves the memory leak. But maybe there is a reason for not doing so..?
