      2. Build and execute the rule.

      Expected behavior: the action part of the rule is not executed.

      Actual behavior: the action part of the rule is executed.

      When executing a rule like (*1) that uses comparison between different-type bound variables (for example, an Integer variable and a String variable consisting of digit characters like (*1-1)), the action part of the rule is unexpectedly fired in executable model though the result of the comparison is expected to be false.

      (*1)

      package com.example.reproducer

import static com.example.reproducer.CommonUtils.getListSize

dialect "java"

rule "rule15a1"
    when
        Order( $target : "3",
               $items : getListSize(items),
               $items != $target )           // ..... (*1-1)
    then
        System.out.println("***** Action of rule15a1 -- $items = " + $items);
end
