I see nothing wrong with your code. At the same time I executed the test
app below and got the expected behavior with regards to the
expect-continue handshaking.

RequestConfig requestConfig = RequestConfig.custom()
.setExpectContinueEnabled(true)
.build();
CloseableHttpClient client = HttpClients.custom()
.setDefaultRequestConfig(requestConfig)
.build();
HttpPost post = new HttpPost("http://www.google.ch/";);
post.setEntity(new StringEntity("stuff", ContentType.TEXT_PLAIN));
CloseableHttpResponse response = client.execute(post);
try {
} finally {
response.close();
}
