The Free Software Definition is kept at
http://www.gnu.org/philosophy/free-sw.html and is linked from the front page
of the Plucker web site at the words "Free Software".

Payment is largely irrelevant.  The freedoms to use, redistribute, modify
and derive are what it's about.  Basically, to be able to use forever and
fix as needed.  Plucker is free software.  JPluck is GPL, ie free software,
according to its web site, although there's a broken link.  Sun Java is not. 
The Sun Java licence also has a nasty legal timebomb, the termination
clause.

Many of them run on free JREs (eg SableVM), can be byte-compiled by free
JDKs, or native compiled by true Java Compilers (eg GCJ).

I think SableVM is only just Java 1.2, let alone 1.4.1_01 yet.  The Java
spec changes quite quickly, it seems, in ways incompatible with previous
minor releases.  Even if one does claim to run Java 1.4.1, given my past
experience, I'm somewhat more sceptical.  I'll wait to hear success reports
from people who have tried before me.
