> The JexlArithmetic class is currently not thread-safe because of the single field:
>     /** Whether this JexlArithmetic instance behaves in strict or lenient mode. */
>     protected boolean strict;
> If this field were made final, and the setLenient() method removed, then the class would be immutable and therefore thread-safe.
> This would mean that JexlEngine would also have to change.
> The class is new to 2.0, so this is the best time to fix this.
