[jdk17u-dev] RFR: 8274471: Add support for RSASSA-PSS in OCSP Response [v2]

[Alexey Pavlyutkin]

> This one is submitted in place of https://github.com/openjdk/jdk17u/pull/248 that was too late to jdk17u
> 
> I'd like to backport JDK-8274471 to jdk17u-dev
> 
> The patch fixes internal error upon verification of OCSP Response signed with RSASSA-PSS
> 
> The original patch applied with minor changes to src/java.base/share/classes/sun/security/provider/certpath/OCSP.java
> 
> - resolved baseline conflict: the original patch was done on top of JDK-8272120: Avoid looking for standard encodings in "java." modules and cannot be applied cleanly although it deletes the changes done against JDK-8272120 (see lines 249-241)
> - imported few required packages
> 
> Verified (20.04 LTS/amd64) with attached [Test8274471.java.zip](https://github.com/openjdk/jdk17u/files/7514663/Test8274471.java.zip). Regression: jdk_security
