Please, review the following fix in "jinfo" launcher.
Issue : https://bugs.openjdk.java.net/browse/JDK-8039080
Webrev: http://cr.openjdk.java.net/~jbachorik/8039080/webrev.00
When switching "jinfo" to utilize diagnostic commands when possible a
combination of launcher arguments was omitted causing "jinfo" fail to
execute the default action (-flags & -sysproperties) against a remote SA
debug server.
The patch fixes this omission. Additionally it contains a refactoring to
make the launcher argument parsing testable via a unit test (testng).
Also, a new test is provided covering the possible argument combinations.
Thanks,
-JB-
