2. The object types from Java's JNI interface:

	jobject
	jclass
	jthrowable
	jstring
	jarray
	jbooleanArray
	jbyteArray
	jcharArray
	jshortArray
	jintArray
	jlongArray
	jfloatArray
	jdoubleArray
	jobjectArray
	jweak

3. The EGLDisplay and EGLConfig types from the EGL API.

These types are uintptr on the Go side because they would otherwise

    val expected = intArrayToByteArray(bytes)
    val actual = bytesOut.readByteString()
    assertThat(actual).isEqualTo(expected)
  }

  private fun intArrayToByteArray(bytes: IntArray): ByteString {
    val data = ByteArray(bytes.size)
    for (i in bytes.indices) {
      data[i] = bytes[i].toByte()
    }
    return ByteString.of(*data)
  }
