Apache Bean Validation will deliver an implementation of the JSR303 Bean Validation 1.0 specification. BVAL entered incubation on March 1, 2010.
The BVAL community is still discussing about the 3 possible graduation scenarios: * Graduate as TLP * Graduate as part of Apache Commons * Graduate under the Geronimo TLP
The codebase is mature and stable, thus there is not much development effort going on atm. Otoh this means that there are not many developers working actively on BVAL.
