The master branch has been broken for a few commits. See Travis: https://travis-ci.org/apache/calcite/branches <https://travis-ci.org/apache/calcite/branches>
The problem only occurs with slow tests (i.e. with -Dgroups=org.apache.calcite.test.SlowTests on the mvn command line) but it happens every time. It’s not the “cached classes” problem that is affecting Jenkins. Let’s make sure that the next commit fixes the build. So, please, no more commits on top of a broken build. Julian
