Hans Cappelle updated RF-7911:
------------------------------

    Attachment: simple-jsf.zip


I was able to reproduce the error with a simple jsf project using the following versions:

myfaces 1.1.4
facelets 1.1.11
org.richfaces 3.3.1.GA

I'm running this code on a glassfish server version: Sun Java System Application Server 9.1_02 (build b04-fcs)

After undeployment the classloaders can't be collected by gbc and like Geert stated before this ClientSelection class is left.

Classloader hierarchy:

sun.misc.Launcher$ExtClassLoader at 0x1aafa2f8 [ 35 classes ]
  ^---- sun.misc.Launcher$AppClassLoader at 0x1aaf6260 [ 54 classes ]
    ^---- com.sun.appserv.server.util.ASURLClassLoader at 0x1aaf6198 [ 6000 classes ]
      ^---- java.net.URLClassLoader at 0x1acf96b0 [ 0 classes ]
        ^---- com.sun.enterprise.util.ConnectorClassLoader at 0x1ad0f900 [ 1 classes ]
          ^---- org.apache.catalina.loader.WebappClassLoader at 0x1d0d4758 [ 768 classes ]
            ^---- com.sun.faces.application.ConverterPropertyEditorFactory$DisposableClassLoader at 0x1d0d8860 [ 1 classes ]

Class left: 

class com.sun.faces.application.ConverterPropertyEditorFor_org_richfaces_model_selection_ClientSelection (84 bytes) : ??

holding HashMap containing an org.richfaces.model.selection.ClientSelection instance

I used jmap and jhat to get this information.

> When redeploying, webapp classloader isn't garbage collected, causing a "java.lang.OutOfMemoryError: PermGen space" after a few times.
> I used a profiler ("yourkit") to see where the issue was and found these 3 classes:
> - org.richfaces.model.selection.ClientSelection
> - com.sun.faces.application.ConverterPropertyEditorFactory$DisposableClassLoader
> - com.sun.faces.application.ConverterPropertyEditorBase
> See attached screen shot for more details.
> I don't know where the 2 com.sun.faces classes come from either, but at least org.richfaces.model.selection.ClientSelection shouldn't be there.
> I saw issue RF-1284 which appears to be very similar, only now this happens in a newer version.
