Thanks Geoffrey! I patched this yesterday with slf4j-jcl and slf4j-nop for no loging. I'll post the mavne dependencies later this morning in case others wish to use non-log4j implementations. :) I did noticeas well that the "scoreCalculator" global is referenced by name from the solver. Want me to file a jira issue on that? It seems strange that the variable name shoudl be static like that to me.
