Running a Java Program

Fri Oct 10 14:54:00 GMT 2003

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.
