   # [DRILL-8257](https://issues.apache.org/jira/browse/DRILL-8257): Resolve Netty lib conflicts
   
   ## Description
   
   The following transitive dependencies in Drill 1.20.* conflict with Drill's own, newer Netty dependencies and need to be excluded.
   
   - jars/3rdparty/netty-transport-native-epoll-4.1.45.Final.jar
   - jars/3rdparty/netty-all-4.1.59.Final.jar
   - jars/3rdparty/netty-codec-http-4.1.59.Final.jar
   
   This PR introduces a Netty BOM. Note that Drill in the past picked up a dependency on every Netty component (netty-all) through the OCI HDFS connector:

> The following transitive dependencies conflict with Drill's own, newer Netty dependencies and need to be excluded.
>  * jars/3rdparty/netty-transport-native-epoll-4.1.45.Final.jar
>  * jars/3rdparty/netty-all-4.1.59.Final.jar
>  * jars/3rdparty/netty-codec-http-4.1.59.Final.jar
> It is not understood what exact conditions are needed for the library conflict to adversely affect a Drillbit, but when they are present it becomes impossible to enable TLS on the user RPC port. One guess is that a class loader race condition decides whether the problem will manifest.
