[rules-users] Disabling strict mode in 5.4

[Joe White]

The exception below is one of thousands like it. The problem is that the
data is coming from a Map and in strict mode mvel is unable to determine
the type. This rule works fine with strict mode off in 5.0.1 and 5.2.

The rule is:

rule "PEL_CHANGELIST_RES.AUTH.Actual First Name" extends
"PEL_CHANGELIST_RES.AUTH.Actual Person Base"
when   
       DalMap($existingValue : this['PERSON.FirstName'] != null) from
$existingPerson
       DalMap($mergedValue : this['PERSON.FirstName'] != null) from
$mergedPerson
       $lowerExisting : String() from $existingValue.toLowerCase()
       String(this != $lowerExisting) from $mergedValue.toLowerCase()
then
       $changeList.add(EncounterConsts.Episode.PersonRole.Person.path);
       update($in);
end

Line 3 of the error message suggests that the parser isn't able to
determine the type of $existingValue as java.lang.String. So, strict
or no strict, the problem might be in the rule. Show?
