Eclipse(I20110514-0800) compiles the following code fine, but generates invalid bytecode which fails at runtime with a java.lang.IllegalAccessError.

A.java
----------
package p1;

class A {
  A() {
  }
}
------------

B.java
------------
package p1;
import java.io.*;
public class B extends A {
 public B() {}

 public void foo(A... args) {
  System.out.println(args);
 }
}
-----------

C.java
----------
package p2;
import p1.B;
public class C {

 public static final void main(String[] args) {
   (new B()).foo(new B(), new B());
 }
}

javac7b138 correctly complains at compile time
