Hello.

1] Probably you don't have to use double buffering

Have a look at:

public final class WakeupOnElapsedFrames extends WakeupCriterion

You can use it to let your application only paint on a new
frame: private WakeupCondition trigger = new WakeupOnElapsedFrames(0);

-> see link to java tutorial at bottom

2] You are sure that it is a painting problen and not
a garbage collection inducted problem?

Run your programm with this java command line

java -verbose:gc <programmname>

If the your programm flickers at the same time as
you see Garbage Collector output then you should
try to avoid objects generated and then garbage collected:
