AU code needs to be updated so as to successfully handle JPRT output dirs' milestones (other than ea).

XML parsing AU methods where the map file is being parsed and build version number is being matched fails if build version number contains 'internal' instead of 'ea', For example , NEXTBLD/NEXTVER fails with "1.7.0_14-intenal-b14." .
