RFR[11] JDK-8206171: Signature#getParameters for RSASSA-PSS throws ProviderException when not initialized

[Valerie Peng]

Hi Brad,

Would you have time to review the fix for JDK-8206171: 
Signature#getParameters for RSASSA-PSS throws ProviderException when not 
initialized?
No source code changes, but just updating javadoc to mention the 
possible failure case.
Otherwise, JCK team expects a parameter object or null being returned.
I filed a CSR to track the javadoc clarification.

Thanks,
