Re: [hibernate-dev] Hibernate 2lc settings in WildFly
I think that it was my mistake to not make this 'immutable-entities' get
its configuration from 'entities', when it's not declared explicitly. I
believe that adding that cache configuration to WF configs is the
easiest way to fix things; though, if users use their own configs, they
won't be notified that something is missing in their standalone.xml -
the same problem as with overridden infinispan configuration, though
this shouldn't be that common and users should pay more attention if
they do that.
AFAIK, there is no place but the default infinispan config where it is
documented which caches need to be defined and what kind of config do
they need. There is also no validation in the code. The defaults are
just in the default config, not in the code, and therefore user can
override all or nothing. Users can even think that all entities are
stored in single cache (while each entity type has its own) .
I don't think that serializing Infinispan configuration into properties
is the best way.
I plan to add some configuration sanity checks as part of HHH-10030, but
I have not thought about any systematic approach, so I'd welcome any
discussion.

The time to do that would of been about four years ago (now we have to
be configuration compatible on the WildFly side at least). Still, not
all applications include Hibernate configuration settings but they do
expect to use a second level cache.
If we were to remove the Hibernate section from [1], where would that
configuration live and what code would deal with that?

In WildFly, that happens to be where we start/stop Infinispan caches,
which makes sense since that is where we also deal with clustering.
