_The call builder.add never returns and doesn't throw an exception either, it simply vanishes without any explanation._
Highly unlikely. You are probably getting a NPE in ExcelParser or a FileNotFoundException but maybe not seeing the exception? Also don't see where you build the KnowledgeBase in your pasted code. If you can create a self-contained test that reproduces the error, please post. Also these types of questions are for the rules-users list.
