Github user rafaelweingartner commented on the pull request: https://github.com/apache/cloudstack/pull/1439#issuecomment-196447656 @rodrigo93 you removed the return type Object (Void) to void; therefore, you have to fix those methods usage, such as the one at line 202 ( caller.setCallback(caller.getTarget().createTemplateAsyncCallBack(null, null));) of classHypervisorTemplateAdapter. There is no return of method "createTemplateAsyncCallBack", so you cannot use its return to set somewhere else.
