Description

I came across a case where the error handling of the JSP scripting doesn't include the message when wrapping the original exception; that means that the details of the exceptions are only available at the deepest level:

Caused by: org.apache.sling.api.SlingException:

It would be much better if the wrapping exceptions contain the details as well.
