>> Problem:
>> Exception is thrown by P11TlsKeyMaterialGenerator.engineGenerateKey method [2], based on result of P11SecretKeyFactory.getKeyType method [3], which only "knows" "ChaCha20" key algorithm, but does not accept "ChaCha20-Poly1305" as algorithm. Algorithm value is passed from SSLTrafficKeyDerivation.LegacyTrafficKeyDerivation class [4], which leads to algorithm field in SSLCipher class [5]. Value of that field comes from cipher name in JsseJce class [6] (ending at first slash, if any).
