Please edit the wiki page and add your annotation scanning requirements/usecases:
http://www.jboss.org/community/wiki/PapakiAnnotationScanningRequirements
"Annotation scanning has a considerable impact in AS deployment and boot time
performance.
There are several subsystems that need to process annotations, for example EJB3, JCA, Web
Services, JBoss Web, JPA, Seam, etc. and that often results either in inefficient
annotation
scanning implementations, extraneous classloading and multiple passes over the same jar
files.
The goal of the Papaki project (formerly JBoss Annotations) is to unify annotation
scanning,
so that it can be performed efficiently and in one pass, with the various subsystem
pulling
annotation information from the Papaki service, thus improving deployment and boot times.
The purpose of this page is to collect requirements from all the projects that would be
interested in plugging into this service, so that we can come up with a comprehensive API
that can serve all the major use cases."
