Description

We are currently using Apache Sling 6 as a war. While trying to upgrade the version from 6 to 7,, changed the attached pom.xml to use "defaultBundleList=7" for the org.apache.sling:maven-launchpad-plugin:2.3.4 (upgraded from 2.0.10 to 2.3.4).

Updated the dependency for org.apache.sling:org.apache.sling.launchpad.base (from 2.3.0 to 2.5.0).
In addition to the default bundles, we are explicitly packaging additional bundles using the attached list.xml. 

The war builds successfully after making the above changes.

But when, the war with the apache sling 7 is deployed to JBOSS EAP 7.4.0, the war fails to deploy and exceptions related to bundle dependencies are seen. Please see the attached server.log file for the errors.

The war for apache sling 6 is successfully deployed on the same JBOSS EAP 7.4.0 server.

 

We tried explicitly adding the javax.servlet bundle to the list.xml at level=0, but it also didn't work. Not sure what is missing.

Note: We are upgrading the sling version, in order to update the Jackrabbit version. We are seeing some Jackrabbit & database connection leak related issues, and thus trying to upgrade the jackrabbit version to the latest. Let us know, if Jackrabbit can be directly upgraded instead. It will be really helpful
