> It looks like that recent changes of IGNITE-1903 are leading to this issue, as we are starting to serialize {{CacheStoreFactory}}, which contains {{PojoFiled}}, which in its turn has transient field accessor. This leads to accessor being null after deserialization. Note, that this happens only when passing {{persistenceSettings}} (not {{persistenceSettingsBean}})
> Works fine with Ignite 2.7.6.
> Probably related to IGNITE-8500
