I have a test program that updates the mouse cursor very often. With Java 1.5 after a while the whole system freezes. Task Manager shows that the number of GDI objects increases dramatically until the limit of 9999. Then the system nearly freezes until command prompt tells a OutOfMemory error.We sell a product based on JAVA that uses code like in the test program. Some customers have huge problems with Java 1.5. Either the scenario described above happens (GDI objects rise), or the whole Java VM crashes.

We have a test case handy which is not showing the exact behaviour but while running the test case for a long while (~5-10 hours) we are facing the following error,
