server.shutdown();
}
```

Your unit tests might move the `server` into a field so you can shut it down
from your test's `tearDown()`.

### API

#### MockResponse

Mock responses default to an empty response body and a `200` status code.
You can set a custom body with a string, input stream or byte array. Also
add headers with a fluent builder API.

```java

    platform.assumeJdk9()
    val applicationProtocolUnsupported =
      object : DelegatingSSLSocket(null) {
        override fun getApplicationProtocol(): String {
          throw UnsupportedOperationException("Mock exception")
        }
      }
    assertThat(Jdk9Platform().getSelectedProtocol(applicationProtocolUnsupported)).isNull()
  }

nativeImageSvm = { module = "org.graalvm.nativeimage:svm", version.ref = "graalvm" }

### Locks

We have 3 different things that we synchronize on.

#### Http2Connection

This lock guards internal state of each connection. This lock is never held for blocking operations. That means that we acquire the lock, read or write a few fields and release the lock. No I/O and no application-layer callbacks.

#### Http2Stream
