Just reporting this for now... A new checkout of the uimaj trunk, plus mvn install, seems to experience intermittent failures in the docbook processing. Sometimes the docbook processing generates "duplicate xml ids", which causes FOP to fail.
Restarting the build after cleaning the project often then succeeds. The build on Jenkins failed at the very end- running RAT. I did a similar checkout from trunk and after some restarts due to docbook failures, did not get a RAT failure. Sigh... -Marshall
