REPRODUCIBILITY :
This bug can be reproduced always.

---------- BEGIN SOURCE ----------
public static <T> void test() {
  final Collection<@NonNull T> c = new LinkedList<>();
  final List<@NonNull String> l = new LinkedList<@NonNull String>((Collection<@NonNull String>) c) {
    // empty
  };
}
---------- END SOURCE ----------

CUSTOMER SUBMITTED WORKAROUND :
Cast only to (Collection).
