However, if {@code getProviderName} or This sentence is repeating what you said in the first sentence of the previous paragraph, so I don't think it is needed. Some suggested re-wordings (and a typo fix on `getKDFParameters` method name), starting this paragraph as: "If the {@code getProviderName} or {@code getParameters} method is called before the {@code deriveKey} or {@code deriveData} methods, the first provider supporting the KDF algorithm and optional {@code KDFParameters} is chosen. This provider may not support the key material that is subsequently passed to the deriveKey or deriveData methods. Therefore, it is recommended not to call the {@code getProviderName} or {@code getParameters} methods until after a key derivation operation. Once a provider is selected, it cannot be changed." ------------- PR Review Comment: https://git.openjdk.org/jdk/pull/20301#discussion_r1746055279
