Sorry for the late reply, most of us were at eclipsecon promoting, p2, p2CUDF and SAT4J :)
What is your level of confidence of stability of this new code. What sort of test suite do you have on the SAT4J side?
Is the old code still in SAT4J? I'm asking because having the two code side by side could help us verify the explanations being produced (maybe by setting a sys property) and thus gain confidence.
