Hmm, I looked at that test as well as the changes that it corresponds to. Given that this PR involves public JCA classes, e.g. the 4 services, having tests for those services and their `getInstance(...)` methods makes more sense as we need to ensure that the javadoc `@implNote` matches the actual behavior. Testing the `permit` call makes a lot sense for checking invalid values though. So, I will explore re-writing the `test/jdk/java/security/Security/SecurityPropFile/InvalidCryptoDisabledAlgos.java` to directly using the `CryptoAlgorithmConstraints.permit` method.
