[rules-users] Deserialzation Error running test example

I get this error running either with Netbeans or Eclispe. I downloaded source from github. Lastest Guvnor too. SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder". SLF4J: Defaulting to no-operation (NOP) logger implementation SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details. java.lang.RuntimeException: KnowledgeAgent exception
