Matteo Casalino created DROOLS-5224:
---------------------------------------
Summary: KieBase build fails with forall patterns containing "not
equal" constraints on Dates
Key: DROOLS-5224
URL: https://issues.redhat.com/browse/DROOLS-5224
Project: Drools
Issue Type: Bug
Components: core engine
Affects Versions: 7.35.0.Final, 7.34.0.Final, 7.33.0.Final
Reporter: Matteo Casalino
Assignee: Mario Fusco
Attachments: forall-not-equal-constraint-on-dates.zip
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:

This is working fine when using Drools <= 7.32.0.Final.
