Consider the following sources:
---B.java
package p;

public class B {
    public interface I {}
}
---
---Test.java
import p.B.I;
---

Then compile and remove the 'I' nested interface:
---
$ javac -d out B.java
$ rm out/p/B\$I.class
$ javac -classpath out -XDdev Test.java
Test.java:1: error: cannot access I
import p.B.I;
          ^
  class file for p.B$I not found
1 error
