No further changes should be posted to Google Code, either in ECJ proper nor in the contrib directories.
Because of the changeover present I am the sole contributor and administrator on github for ecj and for its contrib directories. If you are a contrib maintainer and would like access (of course), please contact me and I will get you set up.
2. I have posted a new version of ECJ (23). Please someone verify that it works properly with the posted libraries.
