Theoretically a KeyStore implementation can store some attributes in clear text and some encrypted, and it's probably not possible to know if there exist any encrypted ones before actually decrypting the entry. Maybe I should say "For a PrivateKeyEntry or SecretKeyEntry, some attributes might only be available after the entry is extracted by the getEntry() method. Try calling the entry's getAttributes() method to see if there are any".

I wonder if someone will interpret this as "after I've called `getEntry` on a private key, I can get the encrypted attributes through `KeyStore::getAttributes`". How about something like "and only available through the {@link KeyEntry.getAttributres} method after the entry is extracted"?
