Subject ClassCastException when starting test server
Date Tue, 18 Mar 2014 18:32:20 GMT
Good morning. I just started using curator. I downloaded and compiled
latest version of curator and using zookeeper 3.4.5. I also use java 1.7.

I embedded single line of code into my java unit test
zkServer = new TestingServer(2181);

Test crashed with exception
java.lang.ClassCastException:
org.apache.zookeeper.server.NIOServerCnxn$Factory cannot be cast to
org.apache.zookeeper.server.ServerCnxnFactory
