cast at call site problem

[Anna Kozlova]

The call foo(Collections.emptySet()); is much more clean I suppose. I just
wonder why the redundant cast leads to compilation error.

Thanks

I believe you want to write this:
foo(Collections.<String>emptySet());

Hello all,

Is it a bug or is it an intentional behavior:
This code compiles
{code}
    void foo(Set<String> s) {}

    void bar() {
        foo(Collections.emptySet());
    }
{code}

but this code doesn't:
{code}
    void foo(Set<String> s) {}

    void bar() {
        foo((Set<String>)Collections.emptySet());
    }
{code}

Lambda build 83.

Thanks
Anna
