Eclipse hung on Mac OS X when clicking on TabItems and then switch to a list

I'm developing an eclipse plugin on Mac OS X 10.7.3. The UI consists of a TabFolder with 4 TabItems, and some other lists. When I switch between the tabs several times and then clicking another list, eclipse will hung. from the Activity Monitor I could see the CPU usage rushed to 100% and Real Mem also keep increasing. The JVM dump is as below:

After investigation i finally found the root cause. It's not caused by the Tab but the List. When clicking on the empty area on a list (the list has more rows than entries), the list.getSelection() will still be the current selected item on Windows, but will be empty on Mac. And when retrieving the value by list.getSelection()[0], eclipse will hang instead of throw ArrayIndexOutOfBoundsException(). I've worked around this issue by remembering the current selection with local variable and set the selection when user clicked on empty areas.
