> When the following conditions are met, a runtime exception is thrown when the following said type is inserted into working memory:
> 1. A ruleflow and rule definition are asserted into the knowledgebase
> 2. The rule definition declares a type as being an "event". (declare myType @role( event ) @timestamp( value ) end )
> 3. The ruleflow references that type in a constraint.
> 4. A rule in the rule definition has a LHS constraint that references that type as an event (i.e., code such as "over window:time( 12M )" is used)
> Attached is a JUnit test that reproduces issue.  The following stack trace is the result:
> java.lang.ClassCastException: org.drools.common.DefaultFactHandle cannot be cast to org.drools.common.EventFactHandle
