Usually, doing "dmake" in a location containing JUnit tests results in
all specified tests being ran. This is undesired in case you're just
working on a single test.
With the integration of CWS undoapi, there's a new target for
selectively running single tests: "dmake javatest_<testname>", where
<testname> is the name of the Java class containing the test, will
just execute this single test.
