Subject Re: ClassCastException when starting test server
Date Wed, 19 Mar 2014 20:07:08 GMT
I can’t build your test due to the repository and parent pom. I suggest doing a mvn dependency:tree
and seeing if something is bringing in an older version of ZooKeeper.

Subject:  ClassCastException when starting test server

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
