Henri Biestro updated JEXL-439:
-------------------------------
Summary: When using reference capture, incorrect scoping when local
variable redefines a captured symbol (was: When using reference capture,
incorrect scoping when local variable shades a captured one in stack frame.)

> Key: JEXL-439
> URL: https://issues.apache.org/jira/browse/JEXL-439
> Project: Commons JEXL
> Issue Type: Bug
> Affects Versions: 3.5.0
> Reporter: Xu Pengcheng
> Assignee: Henri Biestro
> Priority: Major
> Fix For: 3.5.1
>
>
> In relation to JEXL-426, the dynamic scope is wrongly managed when a captured
> variable (ie a lexical variable defined at top-level) is overridden in a
> function (same symbol is used to name local lexical variable) and this
> function calls another that captures the top-level variable.
> With reference capture, when a symbol is captured, the call frame ensures
> captured variables are wrapped into a reference ensuring the 'pass by
> reference' behavior. The culprit here is that when redefining the variable,
> that new variable must be wrapped, not pass the previous one.
