It seems that the examples in the jobs_conf.xml file incorrectly defines the DRMAA runner as

galaxy.jobs.runners.drmaa:DRMAARunner

which should be

galaxy.jobs.runners.drmaa:DRMAAJobRunner

It's really unhelpful if a major change to the way things are run contains these kinds of issues/bugs in the examples, since there is not much on the wikki pages on what are the pre-defined runners......

I had to dig down in the code to figure out the DRMAA runners name...

Hope this helps others getting DRMAA to run in Galaxy after this major update...
