Review Comment:
The overriding is a fair point - I'll move the initialisation of the whole
field into the constructor

Review Comment:
Currently, this method is only called by `ChainingInterceptor` within
Struts, and from what I can tell, these parameters will never be null. Although
it is also a public method. Calling this method with null values is improper
usage and the stack trace will provide better context for such an issue to be
resolved. The previous warning message wasn't very helpful.

Review Comment:
Yeah I agree that it would be better to have the defaults in the code and
properties file be consistent (as well as the accompanying comments in the
properties file). I'll amend this.
