   @eolivelli internally I got code that moved java9's crc32c into bk's package to make it usable with java8. I have implementations of crc32c and adler32 digests, still need to do more perf testing, as time permits.
   
   for proto3 I'd love to keep it compatible with current wire protocol but proto3 is a bit lower in priority list for me at the moment.
   
   I'll take a look at recycler changes, it is possible we already have them in our repo, I need to double-check.
   Somewhat related to netty, we had to add "-Djdk.nio.maxCachedBufferSize=0" jvm flag to prevent out of direct memory errors, and netty 4 is a mojor user of direct memory in our case.
