Resolution: Fixed
https://github.com/apache/commons-jexl/commit/650575a978fec23872cc01472ac0757123d16905
> Handle soft and hard stack overflow
> -----------------------------------
>
> Key: JEXL-274
> URL: https://issues.apache.org/jira/browse/JEXL-274
> Project: Commons JEXL
> Issue Type: Improvement
> Affects Versions: 3.1
> Reporter: Henri Biestro
> Assignee: Henri Biestro
> Priority: Major
> Fix For: 3.2
>
>
> WHAT:
> Since JEXL allows recursion, it would be convenient to stop execution early
> when running towards a stack overflow. In general, scripts don't have much
> use for recursion so this would be a good (soft) safeguard.
> Incidentally, when a function called by a script ends up in a stack overflow,
> it would be nice to catch it and properly propagate it through a
> JexlException.
> HOW:
> Introduce a new JexlException subclass (StackOverflow) that can be thrown
> after catching a (JVM) StackOverflow in Interpreter.interpret().
> The StackOverflow soft limit -ie one that pertains to JEXL only - requires a
> new JexlBuilder option (stackOverflow(size)) and a way to count the stack
> 'height'; easiest/safest seems to put interpreter instance in TLS and
> increment/check a 'frame pointer' member.
