Yes, I will call `jm_createTrustedCertEntry` for every certificate, at least independent from the results of the `SecTrustSettingsCopyTrustSettings` calls.

As I outlined in my initial PR description, point 3, the actual check whether a certificate is self-signed is done in the `createTrustedCertEntry` Java method. So, yes, when there is a self-signed certificate without explicit trust settings, it is always trusted. I thought that this was the intentional behavior even before my changes. However, the difference to the code before is that I look at the certificate and check whether it is a real plain self-signed certificate that can be used for TLS communication - which would be trusted. But what's not trusted now are CA root certificates which also means self-signed but additionally key usage 'keyCertSign' and/or 'cRLSign'. See [this code](https://github.com/RealCLanger/jdk/blob/b14e5f2c78ff4aded84410a2b58d83138349d9ab/src/java.base/macosx/classes/apple/security/KeychainStore.java#L857)

Makes sense?
