The rc looks remarkably good and clean! I did notice one thing (so far): Some of the Jars (e.g. ruta-ep-engine) contain the uimaFIT Jar, which has Notices that are missing from the containing Jar's NOTICE file.
See https://www.apache.org/dev/licensing-howto.html#alv2-dep, where it says: If the dependency supplies a NOTICE file, its contents must be analyzed and the relevant portions bubbled up into the top-level NOTICE file. -Marshall
