Got a fix[1] for Andrews issue which turned out to be a release blocker since it broke performing the release. Also fixed several minor things like javadoc that were wrong with the release. Solving it allowed me to do the publishing in parallel and cut the release time from 20+ mins to 8 mins on my machine.
