Enable SSL certificate revocation checking in OpenJDK 11 - ssl

Question

Is there some quick "declarative" way in Java 11, instead of a tedious manual implementation, to enable checking if a certificate is revoked?
I tried to use properties from this answer:
Check X509 certificate revocation status in Spring-Security before authenticating
with this dummy revoked certificate: https://revoked.badssl.com
but the code always accepts the certificate. Am I doing something wrong or these properties are no more actual for Java 11? If so, do we have any alternatives?
Below is my code:
public static void validateOnCertificateRevocation(boolean check) {
if (check) {
System.setProperty("com.sun.net.ssl.checkRevocation", "true");
System.setProperty("com.sun.security.enableCRLDP", "true");
Security.setProperty("ocsp.enable", "true");
}
try {
new URL("https://revoked.badssl.com").openConnection().connect();
} catch (IOException e) {
e.printStackTrace();
}
}

It seems like those options have to be set before the first request has been performed.
Therefore the following code as standalone Java program throws an CertPathValidatorException: Certificate has been revoked (tested using OpenJDK 11.0.2 x64 on Windows):
public static void main(String[] args) {
validateOnCertificateRevocation(true); // throws CertPathValidatorException
}
However the following code does not cause any errors/Exceptions:
public static void main(String[] args) {
validateOnCertificateRevocation(false);
validateOnCertificateRevocation(true); // nothing happens
}
You can see the changing the options after the first request has been processed isn't effective. I assume that those options are processed in a static { ... } block of some certificate validation related class.
If you still want to enable/disable certificate revocation checking on a per-request base you can do so by implementing your own X509TrustManager that uses CertPathValidator (for which you can enable/disable certificate revocation checking via PKIXParameters.setRevocationEnabled(boolean).
Alternatively there is the solution to globally enable certificate revocation checking and explicitly handle the CertificateRevokedException:
private boolean checkOnCertificateRevocation;
#Override
public void checkServerTrusted(X509Certificate[] certs, String authType) throws CertificateException {
try {
getDefaultTrustManager().checkServerTrusted(certs, authType);
} catch (CertificateException e) {
if (checkOnCertificateRevocation) {
if (getRootCause(e) instanceof CertificateRevokedException) {
throw e;
}
}
}
}
