Re: [hibernate-dev] [OGM] When is AssociationKey serialized?
If you store anything in Infinispan, it should at the very least be
Serializable.
A better solution would be to provide custom Externalizers:

Hi,
I'm wondering why org.hibernate.ogm.grid.AssociationKey implements
Serializable. When is it actually serialized?
When you use Infinispan in clustered mode.
I'm suspecting the answer is "never", as the type of the
"metadata" member
is not serializable, so I'd expect a NotSerializableException to be raised.
Our problem is probably that we don't have integration tests using
Infinispan in modes other than "Local".
I suspect I avoided making them as they make the testsuite slower, but
it seems you just highlighted an important reason to add them :-/
If so, does anything speak against making AssociationKey not implement
Serializable?
It's needed. Also I think it's an important "warning flag" in terms of
design: never consider hooking references to services in such a key,
and strive to keep it as a very simple value holder.
