javax.swing.ToolTipManager causes (eternal) NullPointerExceptions
when JToolTips are enabled on non-showing JComponents, e.g. on
not-yet-shown dialog windows or just-closed dialog windows.
If the bug happens, Swing is unusable, because the main GUI thread
never recovers from the NPEs. ToolTipManager should probably ignore
non-showing components and should be more robust...
I have no small testcase, but a typical stack trace looks like this:
Exception during event dispatch:
java.awt.IllegalComponentStateException: component not showing
at java.awt.Component.getLocationOnScreen() (/opt/gcc40/lib/libgcj.so.6.0.0)
at javax.swing.SwingUtilities.convertPointFromScreen(java.awt.Point,
java.awt.Component) (/opt/gcc40/lib/libgcj.so.6.0.0)

Lillian, can you have a look at this one? I assume this is fixed already.
