It appears that there is a general problem with the latest jdk9 on Jenkins [1]. I modified Calcite jobs to run with a previous version of jdk9 (b181) but things are not that great either since Cassandra tests fail on this jdk [2].
Given this situation, I am thinking that is is better to deactivate the tests on jdk9 at least till INFRA-18694 is resolved. We still have jdk9 tests running on Travis.
