issue with using contains operator on array or collection of double (any )

When using 'contains' operator on array or collection of strings its working fine. But when we use it for an array of primitive type double it gives a classcastexception . Is auto boxing not supported? May be this is fine as it mentioned in the documentation that it works only on Objects. I tried using the array of Double objects, here it doesn't throw an excpetion but the rule wasn't firing. The behaviour was same even if I use a collection of Double objects.

ex:
using Array

rule "OrderArray"
when

Order(valueArray contains 0)

then
System.out.println("OrderArray");
end.

using Collection

rule "OrderList"
when

Order(valueList contains 0)

then
System.out.println("OrderList");
end.
