--------------------------------
Resolution: Fixed

- When binding arguments, check the number of params as the upper limit of
transferable ones; other args will be lost.

> Passing undeclared function parameter can overwrite a local function variable
> -----------------------------------------------------------------------------
>
> Key: JEXL-289
> URL: https://issues.apache.org/jira/browse/JEXL-289
> Project: Commons JEXL
> Issue Type: Bug
> Affects Versions: 3.1
> Reporter: Dmitri Blinov
> Assignee: Henri Biestro
> Priority: Major
>
> The following script
> {code:java}
> var x = function(a) { var b; return b}; x(1,2)
> {code}
> returns {{2}}. The expected behaviour is to return {{null}}.
> As an additional safeguarding measure we may also consider restricting a
> function call with more supplied arguments than the number of declared
> parameters, since, IMO, in a majority of cases this is a bug, like where the
> function definition was changed but the call was not updated accordingly.
