Differences log:

• ant 1.8.x creates empty package-info.class where ant 1.7.x would fail to do so. This is documented at http://ant.apache.org/manual/Tasks/javac.html and is the expected behavior.
• manifest timestamps are slightly different (Created-By - jvm version is formatted differently, I think more human-friendly in 1.8).
