      Description

      Regarding accumulate, min function with BigDecimal does not work as expected when drools.propertySpecific is "ALLOWED".

      The following rule worked with BRMS6.1.4(6.2.0.Final-redhat-13).

      rule "rule1_BigDecimal"
          agenda-group "BigDecimal"
          when  
              accumulate( Fact( $bdVal: bdVal), $minVal : min($bdVal))
              accumulate( Fact( $bdVal2: bdVal, $bdVal2 > $minVal), $minVal2 : min($bdVal2))
           
              $minFact: Fact( bdVal == new BigDecimal($minVal.intValue()))
              $minFact2: Fact( bdVal == new BigDecimal($minVal2.intValue()))
          then
          ...
       end
      

      But after upgrading to RHPAM 7 and setting drools.propertySpecific=ALLOWED, this does not work.
      i.e. rule fires one more time than expected even though there is only one fact at the last iteration.

      This does not happen at least with Long type.
