>Description:
The code below is illegal because x is non final in Local2.a().

gcj reports:

$ gcj -c Local2.java 
Local2.java: In class `Local2$I':
Local2.java: In method `Local2$I.b()':
Local2.java:8: Undefined variable `x'.
         int b() {return x;};    
                         ^
1 error


but the correct error (as reported by javac) is:

Local2.java:8: local variable x is accessed from within inner class; needs to be declared final
>How-To-Repeat:
public class Local2
{
  void a()
  {
    int x;
    class I
    {
      int b() {return x;};    
    }
  }
}
