Operations are processed twice in SwaggerResolver

SwaggerResolver's resolve method is processing operations twice. The pathProcessor.processPaths(); would have already processed operations within the paths. So wondering why the following code process the operations again (removed the code and ran the tests and no test failures).

    if(swagger.getPaths() != null) {
        for(String pathname : swagger.getPaths().keySet()) {
            Path path = swagger.getPaths().get(pathname);
            if(path.getOperations() != null) {
                for(Operation operation : path.getOperations()) {
                    operationsProcessor.processOperation(operation);
                }
            }
        }
    }

Start at SwaggerResolver.resolve and inspect how pathProcessor.processPaths and operationsProcessor.processOperation handle the same operations. Verify whether the repeated loop can be removed, then run the existing test suite; done means operations are processed once and all tests still pass.
