James Leigh created HTTPCLIENT-1425:
---------------------------------------
Summary: Socket Closed Exception When Reading Connection: close
Response Entities
Key: HTTPCLIENT-1425
URL: https://issues.apache.org/jira/browse/HTTPCLIENT-1425
Project: HttpComponents HttpClient
Issue Type: Bug
Components: HttpCache
Affects Versions: 4.3.1
Environment: java version "1.7.0_25"
OpenJDK Runtime Environment (IcedTea 2.3.12) (7u25-2.3.12-4ubuntu3)
OpenJDK 64-Bit Server VM (build 23.7-b01, mixed mode)
Reporter: James Leigh
Fix For: 4.3.2
If the server closes the TCP connection, immediately after sending the complete
response, httpclient-cache will throw socket closed exception.
The server at http://3roundstones.com/ will close the response immediately
after sending the complete response and will include the headers: Connection:
close and Transfer-Encoding: chunked.
HttpClient can deal with this response no problem (using
HttpClients.createDefault). However, CachingHttpClients.createMemoryBound
throws an exception every time I try it. Below is some code (mostly taken of
the docs) that also fails every time. Further down is the stack trace it
produces.
CacheConfig cacheConfig = CacheConfig.custom().build();
RequestConfig requestConfig = RequestConfig.custom().build();
CloseableHttpClient httpclient = CachingHttpClients.custom()
.setCacheConfig(cacheConfig)
.setDefaultRequestConfig(requestConfig).build();
HttpCacheContext context = HttpCacheContext.create();
HttpGet httpget = new HttpGet("http://3roundstones.com/";);
CloseableHttpResponse response = httpclient.execute(httpget, context);
try {
String body = EntityUtils.toString(response.getEntity());
assertTrue(body.length() > 0);
} finally {
response.close();
httpclient.close();
}
