Piotr Zygielo commented on JEXL-428:
------------------------------------
Just out of curiosity, why would one have the expectation {{compare(x, y) ==
-compare(y, x)}}?
Can't {{compare(1, 2)}} be {{-10}} while {{compare(2, 1)}} = {{16}}?
> Make Comparable object high priority while comparing

> I defined a Class with implemented Comparable interface, when compare it with
> a string object, engine does not call the compareTo method but compares by
> string value.
>
> At JexlArithmetic.java L787, if one of the left/right value is string type,
> then compares by string value, I think if the left value is Comparable and
> not String type, using left object's compareTo method first makes more sense.
> Thanks!
