Jar contains ops4j artifacts, causes java.lang.AbstractMethodError in pax-runner [PAXRUNNER-450]

[ops4j-issues]

Ioan Eugen Stan created PAXRUNNER-450

I've made some dependency upgrades to pax-runner so I can provision karaf features. One dependency was pax-url from 1.x to 2.2.0 . The build passes but the artifact is unusable. When run I get this:

-------------------
_
/ /
/ / Oops, there has been a problem!
/ /
/_/ org.ops4j.pax.url.mvn.internal.Activator$1.createConfiguration(Lorg/ops4j/util/property/PropertyResolver;)Ljava/lang/Object;

/__/

-> Exception caught during execution:
java.lang.AbstractMethodError: org.ops4j.pax.url.mvn.internal.Activator$1.createConfiguration(Lorg/ops4j/util/property/PropertyResolver;)Ljava/lang/Object;

----------------

The issue seems to be related to shading. The anonymous inner lass in org.ops4j.pax.url.mvn.internal.Activator has a createConfigurationMethod that receives an org.ops4j.util.property.PropertyResolver type object. However. the MavenConfigurationImpl class is expecting a shaded version: shaded.org.ops4j.util.property.PropertyResolver

final MavenConfigurationImpl config =
new MavenConfigurationImpl( propertyResolver, ServiceConstants.PID );
