I think this is actually the most important piece we have to do, as not doing any annotation scanning at all would most probably be faster than indexing :) | | So we would need to create a ScanningMetaData when e.g. JBossEjbMetaData.isMetaDataComplete(). This then would exclude all non EE5 deployments from annotation scanning without a separate jboss-scanning.xml. As far as i can remember for servlet 3.0 we would need be able to exclude resources on .jar basis as well. This should all be a part of ScanningMetaData - some helper class; e.g. like BMDBuilder --> SMDBuilder. It would then be trivial to build ScanningMetaData and place it into DU. And then PapakiDeployer should take ScanningMetaData into an account while building AE. View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4255063#...
