applications i work with do not save anything without being explicitly told so.
even on windows shutdown. the application simply don't exit and i'll have to
force shutdown and go back save my work or at least deal with the dialog that
popped up. usually the same as closing the application with unsaved changes.
tl;dr Runtime.addShutdownHook() should run the Exit Plugin, done. ..ede

** [bugs:#322] OJ stops without warnings on system shutdown**
**Status:** open

Tested with version 1.6.1 release on Windows.
If there are layers with unsaved edits in OpenJUMP and user ask computer to
shut down, OpenJUMP is closed without any warnings and unsaved edits are lost.
For comparison, Kosmo GIS 3.0 is keeping the computer in such a state that
operating system sends a message that Kosmo prevents the shutdown and asks if
user wants to cancel or do a forced shutdown.
