Subject [jira] [Created] (ODFTOOLKIT-300) Memory Leak in ODF Simple API
Date Fri, 13 Jan 2012 09:53:39 GMT
Memory Leak in ODF Simple API
-----------------------------

                 Key: ODFTOOLKIT-300
                 URL: https://issues.apache.org/jira/browse/ODFTOOLKIT-300
             Project: ODF Toolkit
          Issue Type: Bug
          Components: simple api
    Affects Versions: 0.8.7
         Environment: odfdom-java-0.8.7.jar; simple-odf-0.6.6.jar
            Reporter: Mathias Silbermann
            Assignee: Devin Han


There is a memory leak in the ODF Simple API. I tried both, versions 0.6.6 and 0.6.5. It appears
when running code like the examples on cookbook page

http://incubator.apache.org/odftoolkit/simple/document/cookbook/Manipulate%20TextSearch.html

In short, the call TextNavigation.nextSelection() leads to the leak. When you look down the
method's call stack, you will find that items are added to the static variable "repository"
of the static inner class "Selection.SelectionManager". The added items are never removed
from the repository. One indication is that the method Selection.SelectionManager.unregisterItem()
is never called.

The code works fine if text navigation is done with few documents. But when its run on a server
thousands of times, it will fill the JVMs memory.
