67      * This is confusing, but it's required by our functional test.
68      * What happens is, we have a JUnit test that runs ant to
69      * instrument some classes. When the instrumentation is running,
70      * we want to get the coverage info that is created by exercising
71      * our instrumentation classes.
72      *
73      * So we pass in two different coverage files:
74      * 1. The coverage data file command line parameter. This tells
75      * the instrument task where to write the new coverage data.
76      * 2. The coverage data system property. This tells the
77      * instrumentation inside the instrumented classes where to
78      * keep track of the line hit counts, etc.
79      *
80      * @param task The Java task that will do the forking.
