This program:

class MyClass {
        public static void main (String[] args) {
                System.out.println ("Bla");
        }

compiled with 

gcj -g --main=MyClass -o MyClass MyClass.java

fails to show the source in gdb, showing this:

This only happens for main(); if you set a breakpoint on
'MyClass::main(JArray<java::lang::String*>*)' and run to that, then GDB
will display source.  What you're seeing is actually a bug in gcj
however.
