Resizing JInternalFrame with the keyboard shortcut makes it size grow beyond offscreen.

1.Open SwingSet2 and goto the JInternalFrame tab
2.Click on the button to open a Jinternal frame.
3.Ensure that the newly opened int frame is in focus and press Ctrl-F8.
4.Now click the up,down,left,right arrow keys.
Actual Behaviour- The internal frame gets resized to a larger size and goes off screen.
Expected Behaviour - The internal frame should get resized but it should not go offscreen.
This behaviour which I observed on 6.0b33, I am able to reproduce this till the last locally available build of 6.0b08.
