The MANIFEST.MF file of hibernate-core-5.0.1.Final.jar specifies the following Import-Package:

• org.jboss.jandex;version="[1.2,2)"

WildFly 10.0.0.CR2 ships with Hibernate 5.0.1.Final, and the included version of Jandex is 2.0.0.CR1. It would of course be nice if Hibernate would work with the version of Jandex included in WildFly.

I have manually removed the version dependency from the MANIFEST.MF file with success but I may just not have exercised code that uses the org.jboss.jandex package yet.
