Search your configuration files for instances of
"org.jboss.minerva" and update the package names. In particular, the
XADataSource wrapper class has changed from:
org.jboss.minerva.xa.XADataSourceImpl
to
org.opentools.minerva.jdbc.xa.wrapper.XADataSourceImpl
Shortly you'll be getting ClassNotFoundExceptions instead, so
everyone please keep this in mind if either one happens to you.
