Ognjen Blagojevic commented on TOMAHAWK-1464:
---------------------------------------------
I beleive this is not Tomahawk bug. There in not one reference on
PropertyEditorManager inside Tomahawk code, and the class name
com.sun.faces.application.ConverterPropertyEditorFor_org_apache_myfaces_custom_fileupload_UploadedFile
points that mojarra JSF implementation classes loaded that PropertyEditor, so
they are responsible for unloading it. More to it, after having the same
problem with Mojarra 1.2_08 and Tomahawk12 1.1.9, I tested with other versions
of Mojarra, and both 1.2_09, and 1.2_14 solves the bug.
I recommend changing the status to closed, not a bug, or something similar.

> Key: TOMAHAWK-1464
> URL: https://issues.apache.org/jira/browse/TOMAHAWK-1464
> Project: MyFaces Tomahawk
> Issue Type: Bug
> Components: File Upload
> Environment: myfaces-extensions-1.0.9.jar
> Sun Java System Application Server 9.1_02 (build b04-fcs)
> JDK 1.6.0_11
> Reporter: Hans Cappelle
>
> After redeploying a simple myfaces project with tomahawk extension the
> application server crashes with OutOfMemoryError: PermGen space. Using jmap
> and jhat I discovered serveral classloaders with a reference to an instances
> of org.apache.myfaces.custom.fileupload.UploadedFile were left in memory.
> Because of this classloaders can't shut down properly so after several
> redeployments we get an OutOfMemory.
> classloader hierarchy example (it states 2 classes are left because cleaning
> my test project also fails on a richfaces class):
> ^----
> org.apache.catalina.loader.webappclassloa...@0x1e26b260 [ 853 classes ]
> ^----
> com.sun.faces.application.converterpropertyeditorfactory$disposableclassloa...@0x1e27c788
> [ 2 classes ]
> One of the classes left is:
> class
> com.sun.faces.application.ConverterPropertyEditorFor_org_apache_myfaces_custom_fileupload_UploadedFile
> (84 bytes) : ??
> with a reference to:
> class org.apache.myfaces.custom.fileupload.UploadedFile (84 bytes)
