Does ES Serializer provide optimized serialization format for these Java immutable classes?

Except for UUID, eclipse-serializer includes builtin BinaryHandlers for these classes.

You can find the code for them here:

Thank you! Is there a reason UUID is not optimized - it is very commonly used for entity IDs...

I just tested it and found out that UUID is already fully optimized automatically with the generic handler. Therefore, no custom BinaryHandler is required, it already works out of the box.
If you are interested how generic handlers are created, have a look at the end of the PersistenceTypeHandlerEnsurer.ensureTypeHandler(final Class<T> type) method: https://github.com/eclipse-serializer/serializer/blob/main/persistence/persistence/src/main/java/org/eclipse/serializer/persistence/types/PersistenceTypeHandlerEnsurer.java#L107

Thanks!
