Re: Running a Java Program


Uggghhh! I got confused between overriding and
inheriting static methods. Consider:

------------------------- 8< ----------------------------
public class C
{
  public static void main( String[] args)
  {
    B.main( new String[] { "SNAFU"});
  }
}
------------------------- 8< ----------------------------

Both gij and Sun's JREs run this successfully.

So it looks like a bug in gij (and Oracle JDeveloper
10g Preview)!

Note that GCJ is able to compile it successfully
to a native application but on execution the
same error as gij is printed.
