             Summary: FlumeAppender Stops App from Shutting Down when Newer Version of Netty is Used
                 Key: LOG4J2-265
                 URL: https://issues.apache.org/jira/browse/LOG4J2-265
             Project: Log4j 2
          Issue Type: Bug
          Components: Appenders
    Affects Versions: 2.0-beta6
            Reporter: Jim Tang
         Attachments: zzzzzzzzzzzzzzzzzTest.7z

FlumeAppender(log4j-flume-ng) depends on flume-ng-sdk, which uses netty-3.4.0.Final. When a higher version of netty is used instead, such as 3.5.8.Final or 3.6.5.Final, FlumeAppender will not shutdown properly.

To reproduce the problem (use attached Maven project): 
1. Start your remote flume agent
2. Change the log4j2.xml to your agent host and port
3. press x and hit Enter


Notice how the application continues to run. Press x should break out of the main loop and return from main(), indicating that the application should close. 
The thread holding things up are
Hashed wheel timer #1
New I/O worker #1-8
