PKCS11 regression regarding checkKeySize

FULL PRODUCT VERSION :


ADDITIONAL OS VERSION INFORMATION :
Windows, Linux

A DESCRIPTION OF THE PROBLEM :
There is a problem using PKCS11 for smartcard driver in java 8.

It seems that check regarding key size based on C_GetMechanismInfo was added and in our case PKCS11 smart card driver returns min and max key size with a value of 0 for RSA. And now because of added checkKeySize it fails, because it contains check:

        if ((minKeySize != -1) && (keySize < minKeySize)) {
            throw new InvalidKeyException(keyAlgo +
                " key must be at least " + minKeySize + " bits");
        }
        if ((maxKeySize != -1) && (keySize > maxKeySize)) {
            throw new InvalidKeyException(keyAlgo +
                " key must be at most " + maxKeySize + " bits");
        }

Error is:
Exception in thread "main" java.security.InvalidKeyException: RSA key must be at most 0 bits
at com.sun.security.pkcs11.P11Signature.checkKeySize(P11Signature.java:366)

at java.security.Signature.initSign(Signature.java:527)
at gem_test.Test.signDocument(Test.java:140)
at gem_test.Test.main(Test.java:126)

Relevant mechanism is CKM_SHA1_RSA_PKCS:
  ulMinKeySize: 0
  ulMaxKeySize: 0
  flags: 0 =

In java 7 and before there was no check regarding key size.
Our code worked from java 1.4 till 1.7 and is broken in JDK 8 and JDK 9.
