[jira] [Commented] (BVAL-109) Wrong enforcement that validation groups have to be interfaces

["Matt Benson (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/BVAL-109?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13424565#comment-13424565 ] 

Matt Benson commented on BVAL-109:
----------------------------------

To be pedantic, hat is Hibernate Validator's own documentation, rather than "the Bean Validation specification."  The specification itself says plainly:  "Groups are represented by interfaces."  I am well-aware that Hibernate Validator is the RI and that its developers include many members of the EG including the spec lead, but my evaluation is that this is an implementation-specific issue.  I would prefer that Apache BVal's default behavior remain as-is, although we could possibly enable support with an implementation-specific property.

> The Bean Validation specification does not enforce that groups have to be interfaces. Non interface classes could be used as well, but we recommend to stick to interfaces.

> Suggested fix: remove the check from GroupsComputer.computeGroups.
