Keeping `new Integer` source compatibility with unnamed factory method

[Mateusz Romanowski]

Hi All,
regarding the summary of the last EG meeting (2020-11-04) [1], I can see a
future me being frustrated with having to keep some dusty `javac` only
because of some _mature_ code generation tool that "optimizes" by using
`Integer::new`.

Is the "something special" to keep `Integer::new` source compatibility
adding an `Integer::new` (and similarly `Object::new`) unnamed factory
method?

Sorry if I have missed any material discussions related to such an idea.

Cheers,
Mateusz Romanowski
