[Choco-users] null pointer exception in abstractconstraint.addListner(Unknown Source)

I can't track this error down better than this ... my code is here
http://www.dcs.gla.ac.uk/~pat/cp4/JChoco/hrp/ and a call to java Test
hrp_11_5.dat ends up with some sort of null pointer exception in the
jchoco code via choco.AbstractConstraint.addListner(Unknown Source)

I also have a bizarre error in the following code, specifically file
UMatrix.java http://www.dcs.gla.ac.uk/~pat/cp4/JChoco/speciesTrees/
Here I have an "ultrametrix" constraint as seen in lines 37 to 41 of
file UMatrix.java. In particular there is a redundant constraint that
when added causes JChoco to bomb out on a ClassCastException. The
redundat constraint is A=3DB and C>B and C>A. Remove the last of these =
and
the error goes away!

I am now going to go home and cry and when I come back to work I am
going to volunteer to take on the duties of our Janitor
