As in Gecode, classes should extend the Space class.

Before Gecode/J 1.0.0 the class to extend was the Gecode class. Now
this class is just a collection of static functions.

That is because there is no constraint named lex in Gecode/J. It is
simply called rel:
http://www.gecode.org/gecodej/doc/group__TaskIntIntRel.html

In Gecode the Minimodel package has some additional names for some
constraints, for example for lex. These are not in the Gecode/J
package though. Might be a good idea to add them for the next release.



Cheers,
