This happened at:
Testing : failure validator test: initial trusted key has no params
validatorTestFailure(args, 1); -->ValidateCertPath.doValidate(certs, params, verbose); -->CertPathValidator.validate

Expect:
CertPathValidatorException

Actual:
java.lang.NullPointerException

In the P11DSAKeyFactory.implTranslatePublicKey method, it doesn't check if the returned "params" is null or not before doing "params.getP()" and etc. So in the case the key has no params, this method will throw un-catched NullPointerException.
