[rules-users] Bizarre bug or user error:

[Tom.E.Murphy at wellsfargo.com]

I have the following rule, which is executing in the midst of a complex
data set and a couple hundred other rules:

rule "RS6492.1.2"
	when
		TransactionSummary
		(
			 $LTVRatioPrcnt : LTVRatioPrcnt
		)
		PolicySet
		(
			$maxLTVRatioPrcnt : maxLTVRatioPrcnt,
			maxLTVRatioPrcnt < $LTVRatioPrcnt
		)
	then
		System.out.println("RS6492.1.2 fired. $maxLTVRatioPrcnt
= " + $maxLTVRatioPrcnt + ", $LTVRatioPrcnt = " + $LTVRatioPrcnt);
		// actual actions removed ...
end

In the dataset, there are two PolicySets with maxLTVRatioPrcnt values of
95.0 and 80.0 respectively. The LTVRatioPrcnt in the TransactionSummary
is 85.0.
When my rules run, The above rule should fire only once, for the
PolicySet with 80.0 as its maxLTVRatioPrcnt. However, it fires twice -
once for each PolicySet - with the following outputs:

RS6492.1.2 fired. $maxLTVRatioPrcnt = 95.0, $LTVRatioPrcnt = 85.0
RS6492.1.2 fired. $maxLTVRatioPrcnt = 80.0, $LTVRatioPrcnt = 85.0

How is this possible? Why is the comparison of maxLTVRatioPercnt <
$LTVRatioPrcnt succeeding in both cases, causing the rule to fire on
both PolicySets?
I'm running Drools 5.0.0 with jars dated 15 Jan 09.
Thanks in advance...
