[rules-users] Drools 6.0.1 Negative Patterns in Stream Mode not working

[Mark Proctor]

Can you try 6.1 beta2? And if there is still a bug, please open a jira:
http://mvnrepository.com/artifact/org.drools/drools-core/6.1.0.Beta2

Ideally please submit a self contained unit test, as a pull request. As explained here:
http://docs.jboss.org/drools/release/5.5.0.Final/droolsjbpm-introduction-docs/html/gettingstarted.html
