Ant JunitTask update to support JDK9 modules

Wed Apr 27 16:17:44 UTC 2016

As seen in the modulepath and classpath mixture thread there are many possibilities how to execute unit tests.
I've sumarised them on the ant-dev mailing list in the context of Apache Ant in http://mail-archives.apache.org/mod_mbox/ant-dev/201604.mbox/%3CAFE6C849-0622-44D1-9FF7-3A6CA4832F82@oracle.com%3E
As a result of the discussion I've created a pull request for Apache Ant JUnitTask to support JDK9 modules:
https://github.com/apache/ant/pull/18

Thanks for comments!
I will link them back to the pull request.
