DefaultSlingScript calls request.getReader() which collides with multipart post
parsing later
---------------------------------------------------------------------------------------------
Key: SLING-316
URL: https://issues.apache.org/jira/browse/SLING-316
Project: Sling
Issue Type: Bug
Components: Scripting
Reporter: Tobias Bocanegra
The DefaultSlingScript calls ServletRequest.getReader() in it's service method.
When the underlying 'POST' script tries to access a request parameter of a
multipart post, it fails because the 'reader' is already obtained:
java.lang.IllegalStateException: getReader() already called
