The issue is due to the inability of 3rd party provider (nCipher) on RSASAA-PSS. Currently, in 8u,11u we don't have a mechanism to disable RSASSA-PSS SignatureSchemes in CertificateVerify.
To disable RSASSA-PSS signature schemes, due to issues in 3rd party providers/ application, JDK-8226374 backport would help in 11u and 8u releases.

nCipher added support/ fixed issues related to RSASSA-PSS in 12.60.11. Release notes snippet Changes since V12.60.11 ----------------------- - Support RSASSA-PSS algorithm in JCE - Lower restrictions on external keys for JCE HMAC implementation
