This line throws a NoSuchMethodError:

Answer 1

Yes, anyone who is facing this issue, he should definetely investigate the dependencies with

mvn dependency:tree -Dincludes=org.codehaus.jackson

In my case, I had a jackson dependency on Atmosphere-Socket-io :

        org.atmosphere
        atmosphere-socketio
        2.2.1
        
            
                org.codehaus.jackson
                jackson-mapper-lgpl
            
            
                org.codehaus.jackson
                jackson-core-lgpl
            
        
    

It took me several hours to track that down, thank you all guys for the above solutions which inspired me! Keep up the good work!
