When Taras Glek stepped up and made major improvements to the performance of libjar, we couldn’t resist making him the module owner. libjar hasn’t had an official owner for as long as I can remember. I would occasionally do reviews, as would the networking owners (biesi/bz), but the code was really orphaned code that was unmaintained. Taras is already changing that in a big way. In a quick IRC convention with Brendan today, Taras became the new owner of the JAR code. Congratulations Taras!
