Consider these files:
=== ./P/Outer.java ===
package P;

import static P.Outer.Nested.*;
import static P.Q.C.*;

public class Outer {
  public static class Nested implements I {
  }
}
=== ./P/Q/C.java ===
package P.Q;

public class C extends D {
}
=== ./P/Q/D.java ===
package P.Q;

public class D {
  public interface I {
  }
}
=================

Compiling these files like this:
$ javac P/Outer.java P/Q/C.java P/Q/D.java

fails with:
P/Outer.java:7: error: cannot find symbol
  public static class Nested implements I {
                                        ^
  symbol: class I
  location: class Outer
1 error

The compilation passes when the compilation runs like:
$ javac P/Q/C.java P/Q/D.java P/Outer.java

This is on:
$ javac -fullversion
javac full version "1.9.0-ea-b54"
