>>> Robin what kind of testing have you done on this change? Could you please try to do a fresh conversion of one the smaller repositories, like jtreg, to ensure that we haven't broken anything? The unit tests exercise the Mercurial extension quite a bit, but I really want to ensure we don't mess anything up with regards to the hg -> git conversion.

> Converted the jdk and panama repositories, and they ended up with the same commit hashes, so I think it's looking good. This was using using Mercurial with Python 2, but we can probably keep using that for the conversions.

Ok, great! Yeah, I agree we can keep using Mercurial with Python 2 for the conversion.
