One of good things at Sun is that there are always new technologies to play with, even if it's not related to my daily job. In November, 2008, I did a simple implementation of colorlines game with JavaFX, of course it runs on JavaFX 1.0.
Over one year passed, I know there's a lot of changes from JavaFX 1.0 to JavaFX 1.2. So today I decided to upgrade it. Fortunately, I don't need change one line of codes, it passed compilation with JavaFX1.2 on Netbeans 6.8. However, it had problem during runtime on Windows XP: running as applet is O.K., but running as web start did not show anything. Then I changed to ubuntu linux and opensolaris, everything worked fine. I checked the source codes and Java debug console, but could not find any clue, It's so weird.
Anyway, JavaFX 1.2 showed faster than JavaFX 1.0. I put the codes to Google Code. If anybody can point out the problem I will appreciate that very much.
