Osmosis is using Netty 3, which upstream dropped support for in 2016. Netty is important for security, so it's important to use a supported version: Netty 4.

Unfortunately, significant code changes are necessary to work on Netty 4. I had a go, but the chunked http stuff has changed significantly, and I never understood the old code, so can't really help.

As reported in [https://bugs.debian.org/888255 Debian Bug #888255], netty-3.9 will be removed from Debian which will also cause the removal of the osmosis package.

Osmosis needs to be adapted to use the netty-4.x API.
