In https://bugs.openjdk.org/browse/JDK-8349910 we introduced the QuicTLSEngine for handling QUIC TLS integration. It introduces newer methods in security-libs area related to enforcing AlgorithmConstraints during the TLS handshake. These methods are similar to the ones that were already there for Socket and SSLEngine.

Currently, we don't have tests to verify that the QuicTLSEngine correctly enforces these AlgorithmConstraints. We should add some to match what's there for SSLEngine and Socket.

Artur in the PR review has suggested looking at the existing tests under Please see tests under test/jdk/sun/security/ssl/X509KeyManager for examples.
