How to solve this connectivity configuration cast exception?

Question

I am trying to run some tests on an endpoint of my application but I got a class cast exception.

I get the error when I try to reach the endpoint (localhost) from the same machine I am running my code. I don't have the same problem when I make the request to a different machine (although the code on the server may vary from my local source, I am pretty sure this section does not)

I am using this link as reference ConnectivityConfiguration API

And this is my code:

private synchronized ConnectivityConfiguration lookupConnectivityConfiguration() throws IOException {
    try {
        if (this.localConnectivityConfiguration == null) { 
            Context ctx = new InitialContext();
            this.localConnectivityConfiguration = (ConnectivityConfiguration) ctx.lookup("java:comp/env/connectivityConfiguration");
        }
        return this.localConnectivityConfiguration;
    } catch (NamingException e) {
        e.printStackTrace();                        
        throw new IOException(e.getMessage(), e);
    }
}

I am expecting to get a com.sap.core.connectivity.api.configurationConnectivityConfiguration object when the method is called but instead I get the below error:

java.lang.ClassCastException: com.sap.core.connectivity.apiext.local.LocalConnectivityConfiguration cannot be cast to com.sap.core.connectivity.api.configuration.ConnectivityConfiguration

and I am not sure where this class comes or should be imported from:

com.sap.core.connectivity.apiext.local.LocalConnectivityConfiguration
