[jboss-jira] [JBoss JIRA] (DROOLS-900) java.lang.IncompatibleClassChangeError error while using HashSets

Mario Fusco resolved DROOLS-900.
--------------------------------
Fix Version/s: 6.3.0.Final
Resolution: Done
Fixed by https://github.com/droolsjbpm/drools/commit/a2ab9d4b9
One minor performance suggestion: if I'm understanding correctly you're creating
exactly the same constant sets of values again and again at each constraint evaluation.
Consider to refactor this sets as static and final public fields of a Java class and refer
to this fields in your constraints.

Key: DROOLS-900
URL: https://issues.jboss.org/browse/DROOLS-900
Project: Drools
Issue Type: Bug
Components: core engine
Affects Versions: 5.6.0.Final
Reporter: Pravasis Pattnaik
Assignee: Mario Fusco
Priority: Minor
Fix For: 6.3.0.Final
Attachments: compiled-drl.txt, req.txt
In the compiled drl file we were using (Sets.newHashSet(e1,e2,..)).contains(input) then
we get an exception java.lang.IncompatibleClassChangeError: Class XYZ does not implement
the requested interface java.util.Collection on large input sets.Here XYZ is our input
ruleRequest to be evaluated. If I change it to Sets.newHashSet(e1,e2,..).contains(input)
it fixes everything.
