Frank,

One more bug we found. Enjoy :-)

The compiler does not properly deal with packages and classes that
share the same name.

The following test case has a class called "Foo" and a package called
"Foo". Inside the package "Foo" there is a class "Foo.Bar".

Foo.java:

  public class Foo {
      public static int value;
      public static void op() {};
  }

Foo/Bar.java:

  package Foo;

  public class Bar {
      public static int value;
      public static void op() {};
  }


Ex1.java:

  public class Ex1 {
      public static void main(String argv[]) {
         int value;
         value = Foo.value;
         Foo.op();
         Bar b = new Foo.Bar();
         value = Foo.Bar.value;
         Foo.Bar.op();
      }
  }

Foo/Ex2.java:

  package Foo;
  import Foo; // generates different errors depending on whether this
               // import statement is declared

  public class Ex2 {
      public static void main(String argv[]) {
         int value;
         value = Foo.value;
         Foo.op();
         Bar b = new Foo.Bar();
         value = Foo.Bar.value;
         Foo.Bar.op();
      }
  }


These cause several different errors:


javac Ex1.java:

  Ex1.java:7: No variable Bar defined in class Foo.
      value = Foo.Bar.value;
                 ^
  Ex1.java:8: No variable Bar defined in class Foo.
      Foo.Bar.op();
         ^
  2 errors


javac Foo/Ex2.java:

(without the import statement)

  Foo/Ex2.java:6: Undefined variable: Foo
      value = Foo.value;
              ^
  Foo/Ex2.java:7: Undefined variable: Foo
      Foo.op();
      ^
  2 errors

(with the import statement)

  Foo/Ex2.java:10: No variable Bar defined in class Foo.
      value = Foo.Bar.value;
                 ^
  Foo/Ex2.java:11: No variable Bar defined in class Foo.
      Foo.Bar.op();
         ^
  2 errors
