Investigate how Bean Validation can better support modularized environments such as OSGi. Some issues to consider:
The service loader approach (using META-INF/services/...) doesn't work in OSGi. Currently this is used for bootstrapping and in the future possibly for the registration of validators as well.
How can resource bundles be retrieved from several modules?
How can validation.xml and constraint mapping files be retrieved in modularized environments?
