I don't see a need to make those finals. They are cached and cost at maximum
hundreds of bytes.
Having them cached allows to dynamically change them, which can be handy
sometimes (general remark for other possible cases)

These fields were not modifiable even before my changes; the final keyword I
have added didn't change the external behavior of them. However in general, if
some field can change and the class can be used by different threads then you
have to make sure the class is thread safe (and this is expensive): this is the
main advantage of having (when possible) immutable classes, they are thread
safe at no cost. This is not a matter of memory usage.
Indeed, forgot the _REQUEST_HANDLER_ servletContext attribute
