FULL PRODUCT VERSION :
java version "1.6.0_01"
Java(TM) SE Runtime Environment (build 1.6.0_01-b06)
Java HotSpot(TM) Client VM (build 1.6.0_01-b06, mixed mode, sharing)

FULL OS VERSION :
Microsoft Windows XP [Version 5.1.2600]

A DESCRIPTION OF THE PROBLEM :
I found in internet some example of using of the AffineTransform class and slightly changed it. Unfortunately, after couple of seconds the memory consumtion of this simple application starts to grow constantly and finally it crashes with Access Violation in ntdll.dll or fontmanager.dll

THE PROBLEM WAS REPRODUCIBLE WITH -Xint FLAG: Yes

THE PROBLEM WAS REPRODUCIBLE WITH -server FLAG: Did not try

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Run the provided application. Monitor the memory via Task Manager.

EXPECTED VERSUS ACTUAL BEHAVIOR :
I would expect smooth running of the application, hovewer after couple of seconds it starts to consume memory (takes more than a 1 Gb) and finally crashes with Access Violation
