Adjust test_jmx for updated sjk.jar output
Adjust test_jmx for updated sjk.jar output

New versions of sjk.jar produce slightly different output.

This change makes the tests pass with the new version and should also
work with the older versions.

If not, we'll have to clear the cached version on the Jenkins slaves and
locally.
