[jboss-dev] changes in parsing with xb

[Carlo de Wolf]

Testsuite shows a 100% regression as minimal fails to boot up.

Failed to boot JBoss:
org.jboss.xb.binding.JBossXBException: Failed to parse source: file:/home/hudson/.hudson/jobs/JBoss-AS-5.x-TestSuite-sun15/workspace/Branch_5_x/build/output/jboss-5.1.0.CR1/server/minimal/conf/bootstrap/deployers.xml at 46,56

I'm inclined to do a rollback, because anything coming in *must* be 
backwards compatible.
A log.warn instead of a failure would have been better.

I'll give it 24 hours to be fixed.

Your friendly BOFH,

Carlo
