Optional.orElse(null) ambiguity (original) (raw)

In b72, optional.orElse(null) is ambiguous because it matches both of the orElse forms:

T orElse(T other) T orElse(Supplier other)

For example, this won't compile:

return stream.max(comparator).orElse(null);

Optional needs a concise way to return null, so I suggest:

T orElseNull()
