sorry, I don't see a serverInfo member in HRegionServer..?

I changed the parameter name to "rsCoprocessors" and added a javadoc @param
note; what do you think? Could also just call it "coprocessors" as you
suggested.

bq. Full classnames are canonical and avoid accidental conflict, but are
unwieldy and not so nice to look at. Judgement call, I'd say. I think it
unlikely that for any given deployment two coprocessors will have the same
class name but be in a different package.
I would agree with Andrew and use getSimpleName().

Removed HMasterInterface.java changes at Andy's recommendation: now no
difference with trunk.

changed to getCoprocessors() at Andy's recommendation.

changed; thanks.

removed differences from trunk; you are right: we don't need it here.

Good idea; moved to a new source file: TestCoprocessorReporting.java.

Thanks; removed extra string and added comment with your point.
