Thanks for replying.
This one hangs it:
class HelloWorld
{
public static void main(String argv[]) {
System.out.println("Hello, World");
}
}
So am I to asume that jdb in the jdk1.3.1 port work for others but
not me? If that's the case then where can I get a hold of this patch
set 5 that I hear about?
