Configure Eclipse to compile with javac instead of ECJ?

Question

I have encountered some java8-related code in a maven project that compiles with the javac compiler, but gives compilation-errors in Eclipse (ECJ compiler differ from javac, I suppose).

I'm importing it in Eclipse-Luna with: Import => Maven => Existsing Maven Project

As a quick fix, is there a way to make Eclipse use javac in a maven-project (thus disabling the ECJ-compiler)?

EDIT: Adding a minimal poc-example of compiler-diff.

This code compiles with javac, but the List-initialization gives error in Eclipse: "The target type of this expression must be a functional interface"

package test;

import static java.util.Arrays.asList;

import java.util.List;

public class Test01 {

    private static final List<MyInterface> items = asList(() -> "123", () -> "456");

    public void test01() {
        System.out.println("Hello");
    }

    public interface MyInterface {
        String value();
    }
}

The error disappears if you add typecasts:

private static final List<MyInterface> items = asList((MyInterface) () -> "123", (MyInterface) () -> "456");
