IllegalStateException when sending a new request with a HttpClient that allready sent an aborted request.
Hello,
when i abort a request and after that, start a new one with my
DefaultHttpClient i get the following exception:
29207 [Thread-3] WARN
org.apache.http.impl.conn.SingleClientConnManager - Invalid use of
SingleClientConnManager: connection still allocated.
Make sure to release the connection before allocating another one.
java.lang.IllegalStateException: Revoking connection to
HttpRoute[{}->http://selfhtml.mijabo.de:80]
at org.apache.http.impl.conn.SingleClientConnManager.revokeConnection(SingleClientConnManager.java:345)

at org.downman.download.http.HttpDownload$HttpDownloader.run(HttpDownload.java:536)
at java.lang.Thread.run(Thread.java:619)
Allthough it is only a warning I followed the given adivce and tried
the following after i abort a request:
this.REQUEST.abort();
try {
this.CLIENT.getConnectionManager().releaseConnection(
this.CLIENT.getConnectionManager().getConnection(new
HttpRoute(HttpDownload.this.HOST)));
}
catch(InterruptedException e) {
LOG.warn("Releasing the connection failed for download: "
+ HttpDownload.this.getSource().toString(), e);
}
After that the warning did not appear anymore after starting a new
request, but for some reason this exception appeared as warning when
aborting/trying to release the connection:
40827 [Thread-3] WARN
org.apache.http.impl.conn.SingleClientConnManager - Invalid use of
SingleClientConnManager: connection still allocated.
Make sure to release the connection before allocating another one.
java.lang.IllegalStateException: Revoking connection to

at org.downman.download.http.HttpDownload$HttpDownloader.run(HttpDownload.java:601)
at java.lang.Thread.run(Thread.java:619)
It seems to be the same error. I wanted to ask, what am i doing wrong?
Is it normal to recieve a warning exception when sending requests
after previously aborting one? How can i get rid of this warning?
As a sidenote: I am reusing one and the same HttpRequest (same
instance) and HttpClient multiple times.

Jan Bracker

Hi Jan,
It turned out to be quite a nasty problem.

Fixed in SVN trunk. Please re-test your application against the latest

Re: IllegalStateException when sending a new request with a HttpClient that allready sent an aborted request.
Posted by Jan Bracker <ja...@googlemail.com>.
Well, atleast the error doesn't seem have malicious side effects.
Everything seems to work alltough the error occures and subsequent
requests (when the previous one was not aborted) don't give the error
message anymore.

I just tryed the linked version. When i try to execute a request with
the HttpClient i previously aborted a request from the same exceptions
occures as warning:
47492 [Thread-5] WARN

Make sure to release the connection before allocating another one.

Re: IllegalStateException when sending a new request with a HttpClient that allready sent an aborted request.
Posted by Sam Berlin <sb...@gmail.com>.
Ya, 4.0. There's some snapshots available @ people.apache.org, the
latest of which appears to be:
http://people.apache.org/repo/m2-snapshot-repository/org/apache/httpcomponents/httpclient/4.0-alpha4-SNAPSHOT/httpclient-4.0-alpha4-20080417.184048-7.jar
. I can't guarantee they'll work (as the API is in flux), but if your
code can compile against it and run, and the error goes away, atleast
we can verify that the bug is indeed fixed for the next alpha release.

Re: IllegalStateException when sending a new request with a HttpClient that allready sent an aborted request.
Posted by Sam Berlin <sb...@gmail.com>.
This is likely due to a problem with the last alpha release of
HttpClient. Aborted connections weren't properly released back to
connection managers. It's been fixed, but I'm not sure a new release
was issued.
Is it possible to try building httpclient from source and see if the
problem still occurs?
