And if the translation used invokedynamic to obtain a cached empty array of a particular element type (like lambda metafactory does for lambdas), the overhead to obtain such would be minimal. Good point. I was thinking of clunkier things like Arrays.EMPTYOBJECTARRAY or private synthetic constants. — John
There would at least have to be Arrays.EMPTY_OBJECT_ARRAY and private synthetic constants since the spec. requires that this code works:
public static T[] array(T ... elements) { return elements; }
... String[] strings = array(); Integer[] integers = array(); ... ...
It would be nice to have a method like above in j.u.Arrays then.
