    verifyBuffer(buffer1, 0);
    bufferPool.checkIn(buffer1);
    byte[] buffer2 = bufferPool.checkOut(0);
    assertSame(buffer1, buffer2);
    // Do not checkIn buffer2, but ask for another buffer
    byte[] buffer3 = bufferPool.checkOut(0);
    assertNotSame(buffer1, buffer3);
    verifyBuffer(buffer3, 0);
    bufferPool.checkIn(buffer3);
