> The new ToolBase class calls System.exit when the main routine finishes. That will break
if the application uses threads that need to finish before the jvm exits. The normal semantics
is that the program doesn't finish execution until all of the non-daemon threads exit (including
the main one) and System.exit should never be called except for critical errors.
