      Description

      We are facing a OOM in a SAP Webdynpro Japro/ANT build. After some 7 minutes the process exits with this message:

      java.lang.OutOfMemoryError: PermGen space
      PermGen space

      We discovered a large number of ClassLoaders with "jmap -permstat", which don't get removed.

      The PermSize is 128m in this testcase, if one increases the PermSize the testcase fails later, but it will fail definately.

      You can access the testcase inside SWAN:

      HOST : mde-gy.germany.sun.com
      USER : sap
      PASSWORD : sap
      ACCESS : ssh, telnet
      START : $HOME/go.sh
      COMPILER : /opt/SUNWspro, Sun C++ 5.7 Patch 117830-02 2005/03/30
      JDK : $HOME/jdk150_06, Java HotSpot(TM) Server VM (build 1.5.0_06-ea-b02, mixed mode)
