The software I'm using reports a stack overflow error
when running with JIT. If I disable JIT the software
runs without any problem.

I know that you can not debug applications, but I think it's not an
application problem. I use the progrom muffin 0.7.2 from
muffin.doit.org. It's a Java proxy application.
I have not traced to problem to the final point because I have no time.

If you try the application you need to save the configuration. Then the
program crash with the following exception:

Exception occurred during event dispatching:
java.lang.StackOverflowError
        at org.doit.util.SortedProperties.keys(Compiled Code)
        at org.doit.util.SortedProperties.keys(Compiled Code)
        at java.util.Properties.save(Compiled Code)
        at org.doit.muffin.UserPrefs.save(Compiled Code)
        at org.doit.muffin.FilterManager.save(FilterManager.java)
        at org.doit.muffin.filter.SecretAgent.save(SecretAgent.java)
        at
org.doit.muffin.filter.SecretAgentFrame.actionPerformed(SecretAgentFrame.java)
        at java.awt.Button.processActionEvent(Button.java:257)

        at java.awt.Component.dispatchEventImpl(Compiled Code)
        at java.awt.Component.dispatchEvent(Compiled Code)
        at java.awt.EventDispatchThread.run(Compiled Code)


The problem line is:

public class SortedProperties extends Properties
{
    public synchronized Enumeration keys ()
    {
        Enumeration e = super.keys ();
//------------ Problem line
        SortedList sorter = new SortedList
(StringIgnoreCaseComparer.getInstance ());
//------------
        while (e.hasMoreElements ())
        {
            sorter.addElement ((String) e.nextElement ());
        }
        return sorter.elements ();
    }
}


I added a debug message to the Constructor of the SortedList class. The
message is printed a lot of time and then the java interpreter dies with
the Message I attached as JPG image.


if you have installed muffin it creates some config files in the HOME
directory of the user. You can create a set of filters. The problem occours
if I try to save this filter configuration:

Example:
- start muffin
- press the filter button
- add the stats filter (for example)
- press the save button

You see error only if you start muffin with the java.exe.

I hope this help to get the error message. Otherwise I need to talk to the
author of the program.
