RELEASE NOTES:

security-libs/javax.crypto:pkcs11:

    JDK-8293345: the legacy mechanism check in SunPKCS11 provider is enhanced with service type 

      Native PKCS11 mechanisms which support decryption but not encryption or signature verification
      but not signing are considered legacy and are disabled by default. The legacy mechanism check
      in SunPKCS11 provider is enhanced with the service type. For example, prior to this fix, a
      mechanism supporting encryption, decryption, and verification but not signing, is considered
      legacy and can't be used at all. After this fix, the corresponding Cipher service using this
      mechanism is available since both encryption and decryption are supported. However, the
      corresponding Signature service is not since only verification is supported. To bypass the
      legacy mechanism check, set the PKCS11 provider configuration attribute "allowLegacy" to true
      (default value: false). Note that it is the caller's responsibility to make sure the legacy
      mechanism is not used for the unsupported functionality, e.g. use this mechanism to sign.
