A gjc vs. javac inconsistency:

  class Foo {
    public static final Bar CONSTANT = new Foo.Bar() {
    };
    public interface Bar {
    }
    public Foo() {
    }
  }
 
 
Sun's javac will compile this input, while gjc gives an error:
 
$ kaffe gjc.Main Foo.java
Foo.java:2: non-static variable this cannot be referenced from a static context
  public static final Bar CONSTANT = new Foo.Bar() {

Even though javac compiles it, javap crashes on the result:

Exception in thread "main" java.lang.NullPointerException
