    byte[] bytes = new byte[10 * 1024];
    for (int i = 0; i < bytes.length; i++) {
        bytes[i] = getSamplebyte(i);
    }
    ActiveMQBuffer buffer = ActiveMQBuffers.wrappedBuffer(bytes);
    ActiveMQBufferInputStream is = new ActiveMQBufferInputStream(buffer);
    // First read byte per byte
    for (int i = 0; i < 1024; i++) {
        assertEquals(getSamplebyte(i), is.read());
    }
    // Second, read in chunks
    for (int i = 1; i < 10; i++) {
        bytes = new byte[1024];
        is.read(bytes);
        for (int j = 0; j < bytes.length; j++) {
            assertEquals(getSamplebyte(i * 1024 + j), bytes[j]);
        }

    assertEquals(-1, is.read());
    bytes = new byte[1024];
    int sizeRead = is.read(bytes);
    assertEquals(-1, sizeRead);
    is.close();
