Description

In ZOOKEEPER-4427, Apache ZooKeeper is considering adoption of Logback for logging infrastructure. Logback is dual-licensed under LGPL (category X/disallowed) and EPL (category B/allowable) [1].

Does ZooKeeper need to do something specific to indicate that it chooses to adopt the terms of EPL, and not LGPL? Do we need particular phrasing in the ZooKeeper NOTICE.txt [2] to record our choice of EPL?
