> Both _netty_ dependencies - [_3.2.2.Final_ (from
> _org.jboss.netty_)|http://search.maven.org/#artifactdetails|org.jboss.netty|netty|3.2.2.Final|bundle]
> and [_3.6.3.Final_ (from
> _io.netty_)|http://search.maven.org/#artifactdetails|io.netty|netty|3.6.3.Final|bundle]
> - are found in _lib_ folder:
> {noformat}
> knowak@knowak-dell:~/incubator-storm-0.9.2-incubating/storm-dist/binary/target/apache-storm-0.9.2-incubating/lib$
> ls -al | grep netty
> -rw-rw-r-- 1 knowak knowak 785556 Jun 17 12:38 netty-3.2.2.Final.jar
> -rw-rw-r-- 1 knowak knowak 1202373 Jan 27 11:14 netty-3.6.3.Final.jar
> {noformat}
> as both of them are configured in _pom.xml_:

> [INFO] io.netty:netty:jar:3.6.3.Final:compile

> needs adding an exclusion of _org.jboss.netty_:_netty_
