Using: 
  Eclipse: Mars Release (4.5.0), Build id: 20150621-1200
  Java: JDK 1.8.0_60

Eclipse produces context visibility errors on the following code. The same code compiles and runs in 4.4.2:

// ----------/test/subpackage/A.java
package test.subpackage;

interface A<I> {
	String invoke(I input);
}

// ----------/test/subpackage/B.java
package test.subpackage;

public interface B extends A<Integer> {}


// ----------/test/BugDemonstrator.java
package test;

import test.subpackage.B;

public class BugDemonstrator {

	public static void main(String[] args) {
		// OK
		invoke(new B() {
			public String invoke(Integer input) {
				return null;
			}
		});

		// ERROR
		invoke((Integer i) -> { // Error is here: The type A<Object,Integer> from the descriptor computed for the target context is not visible here.
			return null;
		});
	}

	private static String invoke(B b) {
		return b.invoke(1);
	}
}
