RFR: 8184693: (opt) add Optional.isEmpty

[Stuart Marks]

Hi Vivek,

Please add "@since 11" tags to the doc comments of the four Optional*.isEmpty() 
methods.

Regarding the tests, I don't think the various newly added testIsEmpty() tests 
are useful. The setup in those test files already generates a fairly 
comprehensive set of Optional values from a variety of sources. All the 
assertion checking is performed in the checkEmpty() and checkPresent() methods. 
It should be sufficient to add an assertTrue(isEmpty()) call to checkEmpty() -- 
as you've done -- and also to add an assertFalse(isEmpty()) call to 
checkPresent(). If these assertions are added, the additional testIsEmpty() test 
is unnecessary.

This applies to all four of the regression test files.

Thanks,

s'marks
