Bug introduced by
The method remove() does not seem to exist on object<LinkORB\Component\Etcd\Client>.

This check looks for calls to methods that do not seem to exist on a given type. It looks for the method on the type itself as well as in inherited classes or implemented interfaces.

This is most likely a typographical error or the method has been renamed.
