--------------------------------------------
Hi [~mfusco],
I tried with version 6.4.0-SNAPSHOT (last snapshot example : drools-compiler-6.4.0-20160405.090748-648.jar) and my unit tests do not pass getting a new stack :

> Key: DROOLS-1059
> URL: https://issues.jboss.org/browse/DROOLS-1059
> Project: Drools
> Issue Type: Bug
> Components: core engine
> Affects Versions: 6.3.0.Final
> Reporter: Massinissa BOUZIAD
> Assignee: Mario Fusco
> Priority: Blocker
> Fix For: 6.4.0.Final, 7.0.0.Final
>
> Attachments: DroolsBugReproducerTest.java, reproducerRule.drl
>
>
> In my knowledge base, I have many rules.
> All of them are working very well in production with drools 6.0.1-FINAL even in stress condition hight trafic (arount 40 hits seconds)
> This bug append when we made an upgrade with drools 6.3.0-FINAL which is compatible with jdk8 mandatory in my case.
> So now when I put my rules under stress test (benchmarking) I got this random error.
> Drools is unable to find a query (not always the same one).
> I got this error for 0,6% of my requests.
> *+Following the stack trace : +*
> Unable to find query 'checkAndBindBasket'
