Without commenting on the build changes, I note that jtreg normally 
expects to live in
the following sort of hierarchy, unless you are prepared to use options 
to specify the
locations of other jar files.

bin/jtreg
lib/asmtools.jar
lib/testng.jar
lib/jcov_network_saver.jar
lib/jh.jar
lib/junit.jar
lib/jcov.jar
lib/jtreg.jar
lib/javatest.jar
