--------------------------------------
Sounds good guys, I'll get this committed this afternoon.
This isn't the first bug I've seen related to OSGi classloaders. [~amitsela]
any chance you could dream up a unit or integration test that will
realistically exercise this scenario? Have a look at TestTableMapReduce and
IntegrationTestTableMapReduceUtil for examples. I'm not very familiar with this
environment, so I appreciate any advice you can provide.
> TableMapReduceUtil.findOrCreateJar calls updateMap(null, ) resulting in
