> This is the same issue as https://issues.redhat.com/browse/DROOLS-5100, but on Dates.
> As of Drools 7.33.0.Final, forall patterns with "not equal" (!=) constraints on Dates will break when building the KieBase.
> For example the following DRL:
> {noformat}
>     rule "forall with not equal"
>     when forall(java.util.Date(this != "29-Dec-2019"))
>     then
>     end
> {noformat}
>     
> generates the following error:
> {noformat}
>     java.lang.StringIndexOutOfBoundsException: String index out of range: -1
>     
>     	at java.lang.String.substring(String.java:1967)
