I believe this is a known bug which was fixed in one of 1.4.2 update
releases.

Have you tried the latest update release, 5.0u4?

Try disabling the use of offscreen acceleration by Java2D with
-Dsun.java2d.ddoffscreen=false option.
If that doesn't help, disable the use of DirectDraw completely:
-Dsun.java2d.noddraw=true
