Having trouble with example in the manual

I'm trying to get the example in the manual running. The first thing I
noticed was:

      mg.addExceptionHandler(try_start, try_end, handler, "
java.io.IOException");

which under 5.2 doesn't seem to work. I replaced that with:

      mg.addExceptionHandler(try_start, try_end, handler, new ObjectType("
java.io.IOException"));


After doing this, I get a .class file - but when I try to run the class
under JDK 1.5, I see:

Exception in thread "main" java.lang.ClassFormatError: Illegal exception
table range in class file HelloWorld

        at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:319)

javap lists the exception table as being from 20 to 36 target 36 - which
looks valid to me:

   20:    getstatic    #27; //Field
java/lang/System.out:Ljava/io/PrintStream;
   23:    ldc    #29; //String Please enter your name>
   25:    invokevirtual    #35; //Method
java/io/PrintStream.print:(Ljava/lang/String;)V
   28:    aload_1
   29:    invokevirtual    #39; //Method
java/io/BufferedReader.readLine:()Ljava/lang/String;
   32:    astore_2
   33:    goto    37
   36:    return

Any idea why this might not be working?

Thanks!
