This one is still mysterious - it happens a lot over at StumbleUpon but I
haven't been able to repro on my cluster. I put it in the known bugs list.

Doug says:
"Yes, as an open-source foundation, ASF projects fundamentally produce
source-code releases.  Binaries are optional, sources not.

Overall this sounds like a good plan.  An ASF release needn't be top-quality
and bug-free, but it needs to be voted on.  When voting on a release a
primary concern should be that it contains properly licensed code.  Voters
may additionally wish releases to have a certain level of quality, e.g.,
more for final releases than snapshot releases, but that's not a requirement
of every ASF release."

So until we figure out a way to make a mvn assembly that is
self-hosting/recompilable, let's just vote an an svn export tarball. Of
course right next to it will be a "bin" tarball (which includes src jar,
bin, docs, etc)

Given that I think we have everything in place, I'm going to kick off some
new cluster tests here and start a vote thread.
