------------------------------------
> Unbounded mutual recursion in ACI refinement parsing (StackOverflowError)
> -------------------------------------------------------------------------
>
> Key: DIRAPI-452
> URL: https://issues.apache.org/jira/browse/DIRAPI-452
> Project: Directory Client API
> Issue Type: Bug
> Affects Versions: 2.1.8
> Reporter: Emmanuel Lécharny
> Priority: Major
> Fix For: 2.1.9
>
>
> An authenticated principal with permission to write an _ACI_-syntax value
> submits an _ACIItem_ whose classes refinement is '_not: not: not: ..._'
> repeated ~20k times.
> The syntax checker invokes _check()_, the parser recurses ~40k frames, and
> _StackOverflowError_ unwinds through the schema-validation path, aborting the
> operation and destabilizing the worker thread.
