Felix Meschberger commented on SLING-6502:
------------------------------------------
Hmm, I think the things you are doing here are becoming fragile and needs
proper vetting.
The Launchpad bundle basically has two artifacts:
* Standalone Java Application just bridging into the JVM in a controlled way
* Web Application Archive (WAR), where we bridge to servlet container in
controlled way by adding the Servlet API (and only the Servlet API) to the
framework system packages. The EL and JSP API are not bridged because we have
our own implementation.
I am not sure how the Karaf integration works, but I assume that you have to
control the API deployed in the Karaf system as you are probably not making use
of the Launchpad but directly deploy the Sling bundles into the Karaf framework
as a Karaf feature, right ?
