Hey @andralungu! Thanks a lot for looking into this!
Can you please close this PR and I'll open a new one with the latest
changes.
Regarding returning -1 if the option is not set, I did that so that we
avoid throwing an exception and also because other options like
getIterationAggregator() have a similar behavior. I really don't think it's
such a big deal for one to read the javadoc when using a method :P
Of course, if you have any idea on how we could make this better, please
let me know! (but let's continue the discussion in the new PR).
