Automatic jar scanning (How to disable?)
Hi, I have an app with FreeMarker as a dependency. It's packaged as an uber-jar with deps, using Maven Shade plugin.
AS 7.1.2
FreeMarker 2.3.19
Freemarker has a lot of dependencies, amongst them maven-cobertura-plugin and maven-findbugs-plugin (through jaxen).
Some deps are optional, but when FreeMarker is deployed with an app to JBoss AS, scanning hits classes which use them and AS throws a WARN:

The same with Ant's MatchingTask etc.
And then the deployment fails when Hibernate scans the app for entities:

How can I disable these scans? Prefferably for certain jars or packages. Or is there a better solution?
PS: I know about <exclude-unlisted-classes> in persistence.xml. But I want to specify excluded packages, not the included.
