Branch 1.0 currently includes dependencies that are only reflected in JBossXB trunk. This means the build currently relies on a snapshot release.
In order to run this build against the AS branch 4.0, you'll need manually replace the jboss-xml-binding.jar in JBOSS/client and JBOSS/lib with the one that's in JBOSSWS/thirdparty.
Make sure you get the latest binaries by modifying your local build properties:
