I am experiencing the same problem (environment: tomcat). I choose to
initialize Java2D early during boot of the application server instead having a
memory later when it is being initialized by an app. This class is called as a
wrapper for the original tomcat bootstrap class.
This is only a
Is there any chance of getting a fix for this bug in the somewhat near future?

applications

Unfortunately without some changes in another area
it can not be fully fixed, so I filed this bug:

Dmitri,
Thanks for the quick response and for entering the bug.
I will take a look once it becomes visible.
It might be a good idea to inspect all active (threaded) run-until-JVM-shutdown
subsystems for contextClassLoader reference leaks.

Taras

OK, I've filed a bug (will appear on bug parade in a day):
6489540: The Disposer thread could cause memory leaks in user applications
I've also found out that there's no way to address the first
problem about inheritable thread local storage (see bug's evaluation).
But the second one - with

But before I start asking I need to understand
more about this.
Do you set your own classloader, or is it the default
one?
Better yet, is there any way you could create a small
test case illustrating the problem?
Thanks,

Hi Dmitri,
Is Mustang b89 recent enough to test?
Yes, that should do it.
Out of curiosity, what was changed wrt the Disposer in Mustang? Is the
disposer thread initialized on JVM startup?
The change is
The leak is still there in Mustang b89.

Sure, let's say I manageg to remove all the inheritableThreadLocals.
The next issue is the contextClassLoader that is propagated to the Java2D
Disposer Thread. Which, of course, is exactly the ClassLoader I'd like to
unload (the one with 1GB+ data referenced).
Any idea how to do that?

BTW, the application is a J2EE web app, sometimes serving some graphs with

There isn't such a description. Disoser is an internal mechanism
