    system. We've fixed this with a new package (`okhttp3.java.net.cookiejar`) and a new artifact,
    `com.squareup.okhttp3:okhttp-java-net-cookiehandler`. (The original artifact now delegates to
    this new one.)

    ```kotlin
    implementation("com.squareup.okhttp3:okhttp-java-net-cookiehandler:5.0.0-alpha.12")
    ```

    set("k1", "a", "a")

    // Create an editor, then detach it.
    val editor = cache.edit("k1")!!
    editor.newSink(0).buffer().use { sink ->
      cache.evictAll()

      // Complete the original edit. It goes into a black hole.
      sink.writeUtf8("bb")

    assertThat(cache["k1"]).isNull()
