com.hazelcast.core.HazelcastException: java.lang.ClassCastException: Cannot cast com.hazelcast.client.impl.DefaultClientExtension to com.hazelcast.client.ClientExtension

[sunde...@gmail.com]

Hello all,

I am trying to run integration test cases on one of my application which puts data into hazelcast cache so i am making this application as jar file and running the jar file but when i tried to run the jar file the application tries to connect to hazelcast but it fails saying " com.hazelcast.core.HazelcastException: java.lang.ClassCastException: Cannot cast com.hazelcast.client.impl.DefaultClientExtension to com.hazelcast.client.ClientExtension" i am using hazelcast client version:3.6.2.

Thanks all in advance

Hey,

Can you have a look if you have two different versions of Hazelcast in your classpath? This can happen if you (for example) use Maven to build but do not clean before build.
