test : TestMonitorThread
|
|
Author : Trent Jarvi
|
|
added : Sat Oct 13 17:45:31 MDT 2001
|
|
Problem: Monitor Thread didnt go away in the past. This makes sure
|
|
the thread does exit and is GC's. You can watch the threads
|
|
in a native threads jvm with top.
|
|
todo : There are still some issues with the way BlackBox open/closes
|
|
the ports and the removal of the eventListener.
