-------------------------------------
Created and pushed a
[fix|https://git-wip-us.apache.org/repos/asf?p=olingo-odata2.git;a=commit;h=5f81a5c4c2c79a26619528ed9587de27bf27b7e7].
Should be discussed before merge in master because all implementations which
have override the {{getCallback}} method has to change their method too.
> Incorrect use of generics in {{ODataServiceFactory.getCallback(...)}} method.
