If a change set has a resource pointing to Guvnor in 5.6.0.CR1, the resource is rejected because of http 401 because basicAuthentication is enabled by default. Previously in 5.5.0.Final, in addResourceMapping(Resource resource, boolean notify), there was no check for existence of the resource as if ( notify && newMapping ) { ... } In 5.6.0.CR1, it has been changed to if ( notify && newMapping && ((InternalResource)resource).exists() ) { ..} and the the exists() method simply invokes URL.openStream() which fails with 401 (unauthorized) and the resource is not added. -- View this message in context: http://drools.46999.n3.nabble.com/Http-401-error-in-drools-5-6-0-CR1-tp40...
