[keycloak-user] Infinispan: Custom Keycloak UserStorageProvider throws NotSerializableException in ha-clustered mode

[Dominik Guhr]

Hi everyone,

so I'm on kc 3.4.3.Final and running a custom UserStorageProvider 
("MyAppUserStorage" below) based on the github example jpa storage 
provider. It's all working well in dev-environment, which is not clustered.

But in my clustered production-kc-environment (using standalone-ha, 2 
nodes), the exception below is thrown.
Seems like it has no effect, though, I can successfully use the app, 
even stop one node and everythings working fine.

Now these logentries are at least annoying and I want to know whats 
happening here, so I hope someone could help me out. Do I have to make 
some classes @Serializable or something? (e.g. UserAdapter.java?) to 
work correctly in clustered mode?

Would be great to get some help here! If you need more information or 
code, feel free to ask :)

Best regards,
Dominik
