[rules-users] Deserialzation Error running test example

[richard]

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.
