Verification of OCSP Responses signed with RSASSA-PSS fails with Java 11 LTS

Thank you for reporting this issue. As far as I can tell, it looks like 
the JDK OCSP implementation has not yet been enhanced to support 
RSASSA-PSS signatures.

We will keep an eye out for the bug report you filed but I think it is 
still making its way through our system as I have not seen it yet.
