Description

Solr 8.11.3 updated netty from 4.1.69 to 4.1.99.

While it still contains the netty-transport-native-epoll dependency, the epoll implementation moved to a separate jar in netty 4.1.70.

That jar is included in Solr 9, but it's not been added to the ivy-versions used in Solr 8.

As a result, attemping to use Netty for SSL results in an exception:
