    MessageHeaders messageHeaders = captorMessage.getHeaders();
    assertEquals("Unexpected number of headers", 3, messageHeaders.size());

    String[] headers = { "contentType" };

    for (String header : headers) {
        assertTrue("Missing " + header + " header", messageHeaders.containsKey(header));
        assertEquals("Header " + header + " does not match", messageHeaders.get(header),
