Yes, this is a bug in Jess 7.1p2. Any "test" CE can always be
rewritten by simply attaching the condition to the previous CE;
equivalently, you could rewrite this rule by putting the "test" before
the "or".

Hi,
In the following code, the buy-car rule should not fire. It does not
fire in Jess 7.0, but it fires in Jess71p2. Is there an issue with
the 'or' condition causing the 'test' to succeed incorrectly in 7.1?
Thanks,
Tony
