Bill, are you running all of the ESB unit tests? Since this check-in our CI breaks. Could be coincidental, but worth checking.
I don't know how to run this CI.
All I do is
$ product/ant dist
$ product/ant -f build-distr.xml
There's a problem (just fixed) in the build script that didn't tie the dist rule to the tests. But if you just run ant, the default rule runs all of the unit tests.
