> ArrayBuilder: array type should reflect common class of its entries
> -------------------------------------------------------------------
>
> Key: JEXL-421
> URL: https://issues.apache.org/jira/browse/JEXL-421
> Project: Commons JEXL
> Issue Type: Improvement
> Affects Versions: 3.3
> Reporter: Henri Biestro
> Assignee: Henri Biestro
> Priority: Minor
> Fix For: 3.3.1
>
>
> WHAT:
> The ArrayBuilder (used on syntax like [1,3,5]) tries hard to unbox if
> possible (Integer to int) or keep Number as common class but falls short of
> strong typing for other classes.
> It would be convenient to type arrays using the strongest (in sense of
> abstraction) common class from the entries.
> HOW:
> When detecting entry class mismatch (and not a unboxing or Number), find
> better common class; Object class should only be last resort.
