RSACore$BlindingParameters not using user-provided SecureRandom

[Weijun Wang]

In src/java.base/share/classes/sun/security/rsa/RSACore.java:

   353          BlindingParameters(BigInteger e, BigInteger d, BigInteger n) {
   354              this.u = null;
   355              this.v = null;
   356              this.e = e;
   357              this.d = d;
   358  
   359              int len = n.bitLength();
** 360              SecureRandom random = JCAUtil.getSecureRandom();
   361              u = new BigInteger(len, random).mod(n);

Here, it is not using the SecureRandom passed into init() of either Signature 
or Cipher. Is this a bug we should fix?

Thanks
