Robert:

sun.security.provider.SeedGenerator is part of JDK, so
you could file a bug against it.

I am not clear about which JDK release you are using,
since "rel 5" and "rel 4" are not official release
designations.

Are you using JDK 1.2 or JDK 1.1.7?

We are aware of the broken SeedGenerator in JDK 1.1.7.
This problem will be fixed in JDK 1.1.8 and has already
been fixed in JDK 1.2.

Thanks,

Jan
