Adding jackson-datatype-jdk8 breaks app server integration tests

[snicoll]

If jackson-datatype-jdk8 is added to the classpath, the Glassfish integration test breaks with java.lang.VerifyError: Cannot inherit from final class. Please see server.log for more details. and

[wilkinsona]

Glassfish bundles a rather old and incomplete version of Jackson. As a result, our sample app loads some Jackson classes from the war that's deployed and some from Glassfish itself. This mismatch of versions causes the VerifyError. We can avoid the problem by using a Glassfish-specific deployment descriptor to make the web app's class loader prefer its own classes over those available from its parent.
