I'm having a terrible problem with SecureRandom.

The following program:

   public class Glptest1 {
     public static void main(String[] argv) {
       long startTime = System.currentTimeMillis();
       java.security.SecureRandom.getSeed(20);
       long endTime = System.currentTimeMillis();
       System.out.println("Elapsed time = " + (endTime - startTime));
     }
   }

consistently takes 56 - 62 seconds to execute the SecureRandom.getSeed()
call.  I've checked the PTF Cover Letters and everthing else I could
think of but don't get a hit.

(a)  Has anyone else experienced this problem?
(b)  Can someone try running this on their system and let us know the
results.

I'm running on v4r4 with jdk 1.1.7.

Also, does anyone know if 1.1.8 is available on os/400 v4r4?  If so, how
do I get it?

TIA,
Gary
