-----------------------------------------

             Summary: NullPointerException in Declaration.getHashCode() when getter in LHS and serialize/deserialize package
                 Key: DROOLS-2495
                 URL: https://issues.jboss.org/browse/DROOLS-2495
             Project: Drools
          Issue Type: Bug
          Components: core engine
    Affects Versions: 7.7.0.Final
            Reporter: Toshiya Kobayashi
            Assignee: Mario Fusco


Under the condition:
- A rule uses a getter method in LHS. e.g. "Cheese(type == $p.getName())"
- A package is serialized/deserialized

executing the rule throws NullPointerException.
