The method returns {code} return contains(credentialType, null); {code} If the virtual call resolves to type {{CredentailNode}}, then the {{contains()}} call may result in NPE, because the {{null}} is used as {{algorthmName}} in: {code} return credentialType.isInstance(credential) && algorithmName.equals(((AlgorithmCredential) credential).getAlgorithm()); {code}
