Summary: Memory leak (permgen) in combination with xerces
Key: RF-12601
URL: https://issues.jboss.org/browse/RF-12601
Project: RichFaces
Issue Type: Bug
Security Level: Public (Everyone can see)
Affects Versions: 4.2.2.Final
Environment: Tomcat 6.0.36
myFaces 2.1.9
xerces 2.9.0
Reporter: Michael Heinen
I created a simple web app without any classes, xhtml files, config files.
There are only some jars, including xerces, in the lib folder only.
A "java.lang.OutOfMemoryError: PermGen space" occurs if this app is started,
stopped and restarted.
It does not occur if either richfaces-components-XXX hars OR xerces are removed from the
webApp,

The 4 richfaces jars have to be added manually due to the size limit for the upload.

------------------------------------
Can you try using the jvisualvm tool shipped with the JDK to identify what class is not
being garbage collected on re-deploy? This will help us determine if the issue is a
RichFaces issue, a tomcat issue, or a Xerces issue.

I took a heap dump via jmap and opened it with MyEclipse (Memory Analasys view)
"Merge shorted path to GC Roots" with excluded pahntom/weak/soft/etc references
shows following:
Class Name | Ref.
Objects | Shallow Heap | Ref. Shallow Heap | Retained Heap
------------------------------------------------------------------------------------------------------------------------------------------------------
class com.sun.xml.internal.bind.DatatypeConverterImpl @ 0xfc8f80a0 System Class |

I am not sure why this does not occur without the richfaces-components jars. Are they
using xerces directly or indirectly? I do not see a dependency in the pom file.
This can be reproduced very easy with the attached war and richfaces libs.
Just take a heap dump via jmap (jmap -dump:file=foo.hprof <processId>
Is there anything else I can do?

It seems to be a jdk issue!
See http://java.jiderhamn.se/category/classloader-leaks/ and look for jaxb

------------------------------------
[~mhn] thanks for taking the time to dig in! So if I interpret your report correctly,
this is an upstream issue with the JDK? If so I'll go ahead an close this RichFaces
issue.

Yes, you can close it. It's not a RichFaces issue.
