Local fix

  • Adding the certificate of the signer of the OCSP response to a
    CertStore enables CertPath to verify the signature on the OCSP
    response.
    

Problem summary

  • CertPath for Java 8 fails to validate the signature on an OCSP
    response (from a responder learned from an AIA extension) unless
    the cert of the signer of the OCSP response is found locally
    within a CertStore.
    CertPath commonly learns about OCSP responders from the
    AIA extensions of the certs that it is validating.
    It is impractical for CertPath to demand that the
    cert of the signer or each OCSP response be present within one
    of its CertStores before the signature on an OCSP response can
    be validated.  Typically, that cert is carried on the OCSP
    response itself.
    

Problem conclusion

  • CertPath commonly learns about OCSP responders from the
    AIA extensions of the certs that it is validating.
    The CertPath code has been removed which required CertPath to
    have the cert of the signer of each OCSP response present within
    one of its CertStores, in order to validate the signature on
    each OCSP response.
