I have some code which comiles using Java 8's javac but not eclipse.

Here is an example:

@FunctionalInterface
public interface Accumalator<E> {
  void acum(Container<E> container, E data);
}

public interface Container<E> {
  public void add(E data);

  @SuppressWarnings("unchecked")
  public void add(E...data);
}

public class Binding<E> {
  private final Accumalator<E> function;
  
  public Binding() {
    function = Container::add;
  }
}

The compiler compains about the method reference "Container:add" with the message "Cannot make a static reference to the non-static method add(Object[]) from the type Container".

Removing the overloaded method "public void add(E...data)" on Container resolves the compiler error which is why I beleive it's the cause. Anyhow, when I use javac I am able to compile the code (with the overloaded varargs method) without a problem.
