The javadoc warning is:

/home/gates/src/pig/PIG-1755/trunk/src/org/apache/pig/backend/hadoop/executionengine/physicalLayer/PhysicalOperator.java:306:
 warning - @return tag has no arguments.

The release audit warnings appear to be due to new jdiff files resulting from 
the changes.

The unit tests passed.
