Segementation Violation caused when double clicked on a tooltip. Double clicking on a tooltip is not common or may not be done at all, but if done, causes abrupt closure of application. This can be seen in SwingSet.

Steps to simulate the same..
1. Run SwingSet on solaris.
2. Open tooltip tab pane.
3. keep the mouse on the cow. - causes tooltip to appear.
4. move mouse over tooltip and double click - this causes app to close abruptly.

Below is the output got for the segementation violation

SIGSEGV 11* segmentation violation
    si_signo [11]: SIGSEGV 11* segmentation violation
    si_errno [0]: Error 0
    si_code [1]: SEGV_MAPERR [addr: 0x4]
