Hey,

could you elaborate which issue this PR addresses? Preferably including steps to replicate the issue. Thanks!

Either way, I'd prefer the usage of EntityType#getKey, which seems to be available at 1.15 (not sure if even earlier). That method is annotated as NotNull and is not deprecated - Would be more future proof imo

Very stale, closing.
