The jdk 1.1.1 for Solaris < 2.6 uses currently "green threads" - which don't
support multi processors - threads are scheduled on one.
With Solaris >= 2.6 they invent posix threads, which are able to handle
multi prozessors.

SunOS spelled as Solaris 1.x has no jdk at all.

Yup, SUN gives out a beta for their JVM which will be included in
Solaris 2.6.
I just tryed the jdk 1.1.1 port for Linux - and they use "green threads"
too. But at least it works well on NetBSD/i386 current (as far as I
tested :-).
