[glpk xypron]

Hello Noli,

GLPK Java is currently licensed under GPL v3.

I could (and would be willing to) offer GLPK Java under a less restrictive 
license if the GLPK license were less restrictive.

Actually the license of GLPK does not even allow it to be dynamically linked to 
any software that is not under a GPL v3 compatible license. It would be a great 
alleviation if Andrew could at least add a class path exception as in 

http://openjdk.java.net/legal/gplv2+ce.html

Best regards

Xypron
