Subject [jira] [Created] (HTTPCLIENT-1280) CachingExec catches SocketTimeoutException silently and closes the backend InputStream
Date Mon, 17 Dec 2012 14:04:15 GMT
Francois-Xavier Bonnet created HTTPCLIENT-1280:
--------------------------------------------------

             Summary: CachingExec catches SocketTimeoutException silently and closes the backend
InputStream
                 Key: HTTPCLIENT-1280
                 URL: https://issues.apache.org/jira/browse/HTTPCLIENT-1280
             Project: HttpComponents HttpClient
          Issue Type: Bug
          Components: Cache
    Affects Versions: 4.2.2, 4.2.3, Snapshot
            Reporter: Francois-Xavier Bonnet


When a SocketTimeoutException occurs, CachingExec catches and logs it, then closes the Inputstream:

    at org.esigate.cache.CacheAdapter$HttpClientWrapper.execute(CacheAdapter.java:123)

Then there is no way for the code to know that a problem occurred and if you try to read the
entity you get another Exception:
java.net.SocketException: Socket closed
