Subject [jira] [Created] (HTTPCLIENT-1337) Either DefaultHttpRequestRetryHandler:98 should retry on InterruptedIOException, or DefaultClientConnection's opening() should throw something that can be retried.

Bill Murphy created HTTPCLIENT-1337:
---------------------------------------

             Summary: Either DefaultHttpRequestRetryHandler:98 should retry on InterruptedIOException,
or DefaultClientConnection's opening() should throw something that can be retried.
                 Key: HTTPCLIENT-1337
                 URL: https://issues.apache.org/jira/browse/HTTPCLIENT-1337
             Project: HttpComponents HttpClient
          Issue Type: Bug
          Components: HttpClient
    Affects Versions: 4.2.2
         Environment: On a linux 2.6 x86 box with 4.2.1 http client library.
            Reporter: Bill Murphy
            Priority: Minor


I have seen a stack like the following:

Caused by: java.io.InterruptedIOException: Connection already shutdown 
	at org.apache.http.impl.conn.DefaultClientConnection.opening(DefaultClientConnection.java:121)

	at org.apache.http.impl.conn.DefaultClientConnectionOperator.openConnection(DefaultClientConnectionOperator.java:169)

	at org.apache.http.impl.conn.AbstractPoolEntry.open(AbstractPoolEntry.java:151) 
	at org.apache.http.impl.conn.AbstractPooledConnAdapter.open(AbstractPooledConnAdapter.java:125)

	at org.apache.http.impl.client.DefaultRequestDirector.tryConnect(DefaultRequestDirector.java:640)

	at org.apache.http.impl.client.DefaultRequestDirector.execute(DefaultRequestDirector.java:479)

	at org.apache.http.impl.client.AbstractHttpClient.execute(AbstractHttpClient.java:906) 
	at waggle.core.http.impl41.XHTTP41Session.executeMethod(XHTTP41Session.java:358)  

And I've read Issue #881, but that doesn't seem to contain the fix for my problem. 

I don't really understand the line that throws the InterruptedIOException, as it seems to
me, it should just retry right then. If it cannot retry right then, why doesn't the DefaultHttpRequestRetryHandler
perform a retry under these circumstances?

I cannot make this exception happen with total reliability, but it breaks one of our automated
builds test runs about 2 times per week. I'm hoping I've included enough information to be
of some use, if I can answer any questions or provide any more information (or if there's
something else I should do on my side instead of reporting this as an issue), please advise
me via email as I might not check back with this issue tracking system.

Thanks!
