I've tried using XFire 1.1.1 and 1.2-RC, combined with HttpClient 3.0
and 3.1-alpha1. I get the same result, outlined below, which causes a
complete lockup of a thread. I can't figure out what would cause this.
When making a call via XFire (ClientService.getAppLog()), the current
thread locks up just after printing the following out in the logs:
org.apache.commons.httpclient.HttpMethodBase writeRequest
100 (continue) read timeout. Resume sending the request
I see that this log comes from an InterruptedIOException here:
http://jakarta.apache.org/commons/httpclient/xref/org/apache/commons/
httpclient/HttpMethodBase.html#2004
The stack dump of the locked thread is:

What's very weird is that I am able to drop a JSP (test.jsp) that
makes the exact same call and it completes just fine. This tells me
that there is something environmental about _this_ thread that causes
HttpClient to do this. The call alone is not the issue.
Also, I might add that the XFire call never makes it to the other end
(ClientServiceImpl), as I have a print line there that never gets
invoked. I ran a stack dump on the other side as well, and nothing
stood out (though it is possible part of the request made it through
to XFire's Servlet, and then broke and was no longer in the active
thread dump by the time I forced the dump).
Finally, this request is running over HTTP. I'd really like to figure
out:
1) What that log from HttpMethodBase.writeRequest() is all about
2) Why there would be a perpetual "pause" in the native method, but
no actual visible deadlock.
3) How to fix this :)
