           Summary: PermGen Space OutOfMemory Error after repeated Reload
           Product: Tomcat 5
           Version: 5.5.9
          Platform: PC
               URL: http://www.netbeans.org/issues/show_bug.cgi?id=86407
        OS/Version: Windows 2000
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Catalina
        AssignedTo: tomcat-dev@jakarta.apache.org
        ReportedBy: rich.unger@gmail.com


Using Tomcat's Manager user interface I repeatedly
redployed (the button is labeled "Reload" in the Tomcat Manager UI) a simple web
application and I saw perm gen increase in size (by about 8K) each time.  When
the web application has more classes, the increase is more rapid.

Having downloaded NetBeans 5.0 and tested with the default web application I
cannot re-create this issue. I am guessing the root cause is the same as bug
39090 which is fixed in 5.5.16 onwards. I am therefore resolving it as a duplicate.

*** This bug has been marked as a duplicate of 39090 ***

This was just the default webapp template in the NetBeans 5.0 IDE.  You can
create a new web application in NB, and build a .war file from it and use that.
 That will give you a webapp that grows by 8k per reload.

Just by going to the "libraries" customizer for the project, and adding the
"JSF" library from the default list of libraries, you can make each reload
increase your PermGen space usage by over a megabyte.

It's unclear from the description and linked netbeans bug report whether you are
seeing this issue only when running within netbeans.  Have you confirmed this
behaviour running tomcat outside of netbeans?

There are known issues around reloading of the apps, some are related to Threads
and ThreadLocal references.
Do you have a test case, we'd love to get our hands on it.

Sorry, I paraphrased in the initial description.  The NetBeans bug report does
specifically state, however:
"Using Tomcat's Manager user interface (instead of NetBeans) I repeatedly
redployed (the button is labeled "Reload" in the Tomcat Manager UI) a simple web
application and I saw perm gen increase in size (by about 8K) each time."
