RFR: 8271199: Mutual TLS handshake fails signing client certificate with custom sensitive PKCS11 key

[Alexey Bakhtin]

Hello,

Could you please review the small patch for the issue described in JDK-8271199: Mutual TLS handshake fails signing client certificate with custom sensitive PKCS11 key

I suggest updating the RSAPSSSignature.isValid() method to verify if provided key components can be applied to SunRSASign implementation. 
If not applied, implementation can try to select signer from other providers

Regards
Alexey
