[rules-users] rule condition problem in drools 5.5.0 Final

[Davide Sottara]

I could not reproduce the problem in 5.6 either.
Please try 5.6.0-CR1 and consider upgrading,
5.6.Final will be released - I guess - just after the holidays
and will not have substantial differences from CR1.
On the other hand, if the test fails in 5.6 too, please
submit a reproducer.
Thanks
Davide
