Konrad Windszus commented on SLING-6703:
----------------------------------------
I just redid the test with an AEM 6.3 with a patched POST servlet (exposing the
original servlet) with {{curl -v -F":operation=delete" -F":applyTo=/libs/*" -u
test:test http://localhost:4000}} and I get back
{code}
* Rebuilt URL to: http://localhost:4000/
* Trying ::1...
* TCP_NODELAY set
* Connected to localhost (::1) port 4000 (#0)

This looks correct, as /libs/.servlet is provided by a ResourceProvider not
backed by the JCR itself (and therefore not protected through ACLs)

> Project: Sling
> Issue Type: Improvement
> Components: Servlets
> Affects Versions: Servlets Post 2.3.14
> Reporter: Konrad Windszus
> Assignee: Antonio Sanso
>
> Currently {{AbstractPostResponse.setError}}
> (https://github.com/apache/sling/blob/4df9ab2d6592422889c71fa13afd453a10a5a626/bundles/servlets/post/src/main/java/org/apache/sling/servlets/post/AbstractPostResponse.java#L221)
> always ignores the given {{Throwable}} and just creates a new generic
> {{SlingException}}.
> To e.g. allow {{SlingPostProcessor}} to throw meaningful exceptions which
> occur in the response body, the given exception should not be wrapped but
> just the given throwable's message text should be given out in the document.
