> Add JexlFeatures to control namespace functor auto-instantiation
> ----------------------------------------------------------------
>
> Key: JEXL-469
> URL: https://issues.apache.org/jira/browse/JEXL-469
> Project: Commons JEXL
> Issue Type: Improvement
> Affects Versions: 3.7.0
> Reporter: Henri Biestro
> Assignee: Henri Biestro
> Priority: Major
> Fix For: 3.7.1
>
>
> When a namespace is declared as a Class or a fully-qualified class name
> string, JEXL automatically instantiates it into a functor via reflection the
> first time it is used. This behaviour has no opt-out.
> This improvement adds JexlFeatures.namespaceInstantiation(boolean) to control
> that behaviour. When disabled, only static methods of the bound class are
> reachable and no constructor is invoked. The default is true, preserving
> backward compatibility.
> As a related hardening, a string namespace resolved to a class now goes
> through the permission-aware JexlUberspect.getClassByName rather than loading
> the class directly, so permission rules apply consistently to class-name
> namespace bindings.
