Fix eclipse compilation (backport of #66047)

[nik9000]

Looks like we've hit another "funny" eclipse compiler error. I filed
https://bugs.eclipse.org/bugs/show_bug.cgi?id=569557 , but short version
is that the following code compiles with javac and not eclipse:

package test;

import java.util.function.Supplier;

public class Test {
	private final Object o = new Object();

	private class Inner {
		public Inner() {
			this(() -> o);
		}

		private Inner(Supplier<Object> o) {}
	}
}

Specifically the outer class's o can't be refered to in the lambda.
This stops us from doing that in ML so eclipse can be happy again.
