@pedro-martins On line 503, It is not a function but It is a way to define
callback method. It has been used all over the cloudstack code. On line 504,
context was set and will be available in callback method
'createTemplateAsyncCallBack'. So there are no chances of null pointer
exception on line 598. If there was any chance of null pointer exception, it
would have happened in my test setup.
