> As discussed on QPIDJMS-315 and before in ARTEMIS-1099, using Netty 4.1.15 and below
with its epoll transport module present can lead to a warning being emitted on a 32bit JVM,
since only a 64bit variant is provided but attempt was still made to load it during the availability
checking, leading the JVM itself to emit a warning about the architecture mismatch.
> The PRs https://github.com/netty/netty/issues/7150 / https://github.com/netty/netty/pull/7163
addressed this in Netty 4.1.16, making the archiecture part of the native library name, so
it doesn't attempt to load the native 64bit library on a 32bit JVM.
> QPIDJMS-318 covered the update to Netty 4.1.16 which incorporated this fix.
