fastjavac: version 4.0, "11/04/00-10:39", build #461

A static inner class cannot extend a non static inner clas!

However, fatjavac compiles with no errors and produces a .class file 
which cannot be loaded and produces the followin error:

Exception in thread "main" java.lang.VerifyError: (class: InnerClassBugTest,
method: main signature: ([Ljava/lang/String;)V) Expecting to find object/array
on stack


The external java compiler correctly detects the error.

Here is a buggy java file with the error.


------------------------------
public class InnerClassBugTest {
    
    
    public InnerClassBugTest() {
    }
    
    // This inner class should be static
    public class father {
        
    }
    
    public static class son extends father {
        public son() {}
    }
    
    public static void main(String[] args) {
        new son();
    }
    
}
