[JAVA2D] SwingSet2 JColorChooserDemo

Hello,

I'm facing a strange behavior of the Swingset2 JColorChooser demo. The
animated bezier curve flashes around the screen instead of animating
smoothly.

This happens with jdk 1.5.0_03 , _04 on three different machines:

1) P4 3.2Ghz-HyperThreading- 1Gb ram, Matrox Parhelia, WinXP - jdk1.5.0_03
2) P4 3.2Ghz-HyperThreading- 1Gb ram, Nvidia FX 5200, WinXP - jdk1.5.0_04
3) P4 3.2Ghz-HyperThreading- 1Gb ram, Nvidia FX 5700, WinXP - jdk1.5.0_04

Further tests outlined that the problem is related to P4 Hyper Threading.
When the HT is ON than the refresh problem pops up. If HT is OFF then the
spline runs smoothly on the screen.

I hope someone of the Java2D team can give it a try to see what happens.

Cheers,

Mik

Hi Michele,

I believe this is a known problem with the demo itself.

Thanks,
Dmitri
