I have got this bug on every applet I have tested to compile and run. I have a single CPU computer and running jdk 1.5 and eclipse 3.1.1. I only get it the first time I run it after I changed anything in the code. And I can very easy reproduce the bug with minimal code.

Could you please try this on the latest mustang (Java 6) build from http://mustang.dev.java.net ?
This bug appears to have been fixed in mustang b62.
Thank you,

I was having the same problem with JDK 1.5 (with all updates including 10th) on machines with dual-core CPUs. I am using JDK 1.6 RC, and it seems that the bug is fixed now.

Sorry I can not figure out how to fix this problem. Is there any one to tell the solution in a easier voice.
Submitted On 30-SEP-2009
The solution is easy: stop using Java for graphics and use Flash/Flex.
PLEASE NOTE: JDK6 is formerly known as Project Mustang
