CUSTOMER SUBMITTED WORKAROUND :
After JToolBar hide, invoke setRollover(false) and setRollover(true) will solve this problem, but I think this should be handle in JToolBar UI class.

Add a ComponentListener in JToolBar UI class and reset all Button border when JToolBar has removed from it's parent container.
