I think we went though that discussion of formality a while back; the
conclusion being without a formal specification of semantics.

What tends to burn code is the implicit expectations of behaviour -stuff
that was never stated to be true, but which turned out to be so for a while.

I view all these bugreps as a sign of Bigtop's value to the release
process -from that point of view: well done.

One thing I would like to see for build and test is the 0.23+ JARs in
the public mvn repository, including the test ones (without any log4j
files), so that downstream projects can work with them easily. I can see
the 0.23.0 SNAPSHOT artifacts in the apache repository, but given the
way M2 handles such things, I'd rather stable versioned releases
