incompatible in unix? calculating cpu time in swing ?

I am confused about the fact that when I run my swing program in netbeans on windows xp platform. The buttons have the ability to traverse the focus around using TAB key. But when I run the program in unix, the TAB key has no effect on the focus at all. I really want the TAB key to work !!!

Also, anyone knows if java has a method to calculate cpu time? I can only use System.currentTimeMillis() to measure the wall clock time. But I will need the actual cpu time spent on that particular thread.

Can somebody help ? Thanks !!!
