Description

Consider the following:

Class c = Integer
Predicate p

p = c::isInstance
assert p.test(null) == false
assert p.test('xx') == false
assert p.test(1234) == true

p = c.&isInstance
assert p.test(null) == false
assert p.test('xx') == false
assert p.test(1234) == true

p = o -> c.isInstance(o)
assert p.test(null) == false
assert p.test('xx') == false
assert p.test(1234) == true

p = { c.isInstance(it) }
assert p.test(null) == false
assert p.test('xx') == false
assert p.test(1234) == true

The reference and pointer groups fail while the lambda and closure groups succeed. This is excerpted from GROOVY-10053 testing without SC.
