-------------------------------------

Solution available here: https://github.com/ryanemerson/infinispan/commit/853cf0a4d496216725f37d1fa15a4c793fb7b605

However, it won't currently work as it's blocked by IPROTO-103.

> Currently the RocksDB purge method stores multiple keys that expire at the same time in a ArrayList associated with the expiry time. This is currently marshallable because ArrayList is serializable and we utilise Jboss-marshalling, however ISPN-10354 means this is no longer possible in embedded mode when `infinispan-jboss-marshalling` is not present. Therefore, we should create a `ExpiryBucket` that can be marshalled via the persistence marshaller i.e. protobuf based.
