A few more comments.

src/java.base/share/classes/sun/security/pkcs/SigningCertificateInfo.java line 133:

You could also mark these as `final` and add an `else` block to the ctor which sets them to `null`.

src/java.base/share/classes/sun/security/pkcs12/PKCS12KeyStore.java line 2319:

Personally I prefer seeing "continue" here - it makes it clear that none of the remaining code in this loop is relevant.
