RFR: JDK-8144332: HSDB could not terminate when close button is pushed.

[Yasumasa Suenaga]

Hi all,

When I ran HSDB through jhsdb, I could not terminate it through window close button.
HSDB starts WorkerThread. It will be terminated when Exit menu is selected.
However, it will not be shotdown when HSDB is terminated through close button.

I've created a patch and uploaded webrev:
  http://cr.openjdk.java.net/~ysuenaga/JDK-8144332/webrev.00/

Could you review it?

I'm jdk 9 committer, however, I could not access JPRT.
Thus I need a sponsor.

Could you help?


Thanks,

Yasumasa
