Getting error pulling RESTCONF URL

When I pull a RESTCONF URL that refers to a top level container in a specific sub-module I'm getting an error:

The URL is:

http://localhost:8080/restconf/operational/opendaylight-inventory:nodes/node/ncs/yang-ext:mount/tailf-ncs:devices/

The error is:

HTTP Status 500 - java.lang.NoSuchMethodError: javax.ws.rs.WebApplicationException: method <init>(Ljava/lang/String;Ljava/lang/Throwable;)V not found

type Exception report
