JDK: JDK1.4.0-Beta44

Tab functionality in JTextPane is broken. Tab jumps between
different windows inside the frame instead of tabbing through JTextPane

To reproduce bug:
1- Compile and run the following code
2- Go into the first JTextPane
3- Press the TAB key once
4- Note that TAB is not displayed in the first JTextPane
5- Note that TAB is displayed in the second JTextPane
5- Repeat STEP3
6- Note that TAB keep jumping to the next JTextField
