I’ve tracked down the place where this warning is logged. It’s in MetadataBuilderImpl, line 626: [https://github.com/hibernate/hibernate-orm/blob/main/hibernate-core/src/m...] Analyzing the code, it gets a setting, specifies a default value in case the setting has not been set, which is SharedCacheMode.UNSPECIFIED, and then, when getting this default value, logs a warning saying that this this value is deprecated.
