No problem with concurrency, as I said they have no state. A lot of
patterns would make sense, but JSF API/taglib doesn't seem to facilitate
any of them, hence my question.

Wouldn't singletons need to be multi-threaded otherwise you will get
probems with concurrency. Would a pooled resource pattern make more
sense if you validators/converters are costly to create?

Subject: singleton validators and converters



Is there a standard way/practice to have singleton validators and
converters? Those are mostly stateless and in a large application with
aggressive input validation, it would make sense to avoid creating them
on the fly each time and for each user.
