 *    "www.squareup.com".

 *  * **A set of hostnames.** These are in the certificate's subject alternative name (SAN)
 *    extension. A subject alternative name is either a literal hostname (`squareup.com`), a literal
 *    IP address (`74.122.190.80`), or a hostname pattern (`*.api.squareup.com`).
 *

 *  Fix: Don't crash with an `InaccessibleObjectException` when running on JDK17+ with strong
    encapsulation enabled.
 *  Fix: Strictly verify hostnames used with OkHttp's `HostnameVerifier`. Programs that make direct
    manual calls to `HostnameVerifier` could be defeated if the hostnames they pass in are not
    strictly ASCII. This issue is tracked as [CVE-2021-0341].
