Hello,

the cache factory startup method silently handles exceptions.

org.hibernate.cache.spi.AbstractRegionFactory.start(SessionFactoryOptions, Map)

On error, exceptions are caught and the region factory stays in non started mode without logging a reason.
Later on during SessionFactory initialization, it will fail because regionFactory is not in started mode.

It would be helpful if the regionFactory logs its' failure with stacktrace.

Kind regards
