Support java.util.Optional as parameter type in resource methods

Jersey fills in missing optional resource method arguments with 'null'. Dealing with "possibly null" variables can be a bit of an annoyance, so more than often I do

Optional optArg1 = Optional.ofNullable(arg1);
Optional optArg2 = Optional.ofNullable(arg2);
...

at the top of my resource methods. This opens up for use of many convenience methods such as map, orElse, orElseThrow, ifPresent etc.

So, request for enhancement: Let Jersey handle java.util.Optional as parameter type in resource methods directly.
