remove this extraneous method. the superclass already has this method, and this overriding method is the identical code.
BZ 1089757:
* default timeout to wait for process to stop is now 30s, not 10s.
* add some logging.
* add a sysprop to let user configure how long to wait for a process to stop.
* don't abort the install if the components failed to stop at the end. This just means the components are still running after the install ran. There will be a message spit out letting the user know the component might still be running.
