In the context of the goal is to declaratively identify tests that do or do not benefit from additional test flags renaming the `createjavaProcessBuilder` method does not further that goal.

The method name and javadoc of `createjavaProcessBuilder` do not imply that the test options are consulted or used; it only says it creates a ProcessBuilder, and does not promise or document more than that.  The javadoc should probably describe the use of the the three properties that modify the way that the java is launched.
