--------------------
> Make JexlArithmetic immutable (and threadsafe)
> ----------------------------------------------
>
> Key: JEXL-83
> URL: https://issues.apache.org/jira/browse/JEXL-83
> Project: Commons JEXL
> Issue Type: Improvement
> Reporter: Sebb
> Assignee: Henri Biestro
> Fix For: 2.1
>
> Attachments: JEXL-83.patch
>
>
> 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.
