    writing it has test supersource but no prod supersource.

    GWT happens to use the prod .gwt.xml, so it looks for no supersource for
    tests, either. This causes it to fail to find AtomicLongMapTest.

    Our workaround is to tell GWT that util.concurrent and all other packages
    have prod supersource, even if they have none. GWT is happy to ignore us
    when we specify a nonexistent path.

 *  Fix: Don't crash if Conscrypt returns a null version.
 *  Fix: Include the public suffix data as a resource in GraalVM native images.
 *  Fix: Fail fast when the cache is corrupted.
 *  Fix: Fail fast when a private key cannot be encoded.
 *  Fix: Fail fast when attempting to verify a non-ASCII hostname.
 *  Upgrade: [GraalVM 21][graalvm_21].
 *  Upgrade: [Kotlin 1.4.20][kotlin_1_4_20].
