Colvin Cowie created SOLR-17168:
-----------------------------------
Summary: Netty epoll implementation not included in 8.11.3
Key: SOLR-17168
URL: https://issues.apache.org/jira/browse/SOLR-17168
Project: Solr
Issue Type: Bug
Security Level: Public (Default Security Level. Issues are Public)
Affects Versions: 8.11.3
Reporter: Colvin Cowie
Solr 8.11.3 updated netty from 4.1.69 to 4.1.99.
While it still contains the [netty-transport-native-epoll
dependency,|https://github.com/apache/lucene-solr/blob/9ebfd2b0a584faa072685fff4956f05b52e60d7c/lucene/ivy-versions.properties#L120-L129]
the epoll implementation moved to a [separate
jar|https://mvnrepository.com/artifact/io.netty/netty-transport-classes-epoll]
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:
