[bv-dev] support for non-standard Java beans

Hi Andrei,

You've come to the right place to discuss such proposals.

Supporting other models than JavaBeans is an interesting idea, we've
also been thinking about it as part of the reference implementation.
It's too late for BV 2.0, but it's definitely something I could
envision in a future spec revision.

Thanks; we should definitely explore that within the RI.

There's also https://hibernate.atlassian.net/browse/HV-1000 which
takes the thought a bit further and aims at supporting models not
backed by POJOs at all, but e.g. maps (with key/value pairs as
properties), JSON strings etc. Naturally, annotations couldn't be used
as metadata source for such models, instead constraints would have to
be declared programmatically.

Perhaps you'd be interested in contributing and exploring the property
resolver SPI you suggest?
