<AWT Dev> [9] Review request for 8014755: [TEST_BUG] frames didn't closed after execution some awt/dnd/ tests

[Oleg Pekhovskiy]

Hi Petr,

thank you for the review, here are my thoughts:

1. I added new method that way after analyzing the other methods and 
their usage in jtreg tests. If you look at getExecutionCommand() you 
could see the similar solution. Indeed my changes don't break the 
previous usages of ProcessCommunicator. It's also possible to perform 
bunch run, but of course without the termination ability. Another issue 
is that we must kill a child VM explicitly if it doesn't exit 
automatically, but we must do this only after test sequence is passed.
jtreg doesn't kill child VMs on timeout, this is the known problem 
(that's why this JIRA issue exists).

2. I decided to leave it as is, as main classes in these tests are used 
in two cases: applet itself and the main class for child VM.

3. I found this mistake and added it to the second version of fix.

Regards,
Oleg
