  java.lang.IllegalArgumentException: Test returns a com.acme.

Local fix

• Use the debug mode of the Eclipse "Java Application" launcher
  instead of the "Java Application with Rules" launcher.
  

Problem summary

• some variable not having default values are initialized with
  incorrect value . This lead to errors when the engine tries  to
  parse the ruleset
  

Problem conclusion

• The code is fixed
  

Temporary fix
