Modified: proposal/embed/src/java/org/apache/tools/ant/helper
ProjectHelperImpl2.java
Log:
Port some changes from the main branch ( now entity tests pass )
Since embed should run in ant1.5 - I duplicated some of the new
methods in ant16. If ProjectHelper2 will move to the main branch
this needs to be removed ( and some other stuff too )
