Description

I have a client concurrently making several PUT requests to a server. This server returns 204 for these requests. Occasionally, I'll get a ConnectionClosedException. Oddly enough, these exceptions go away if I change the server to return 200.

In the debugger, when I hit the following line, I see that entry.isClosed() is true:
http://grepcode.com/file/repo1.maven.org/maven2/org.apache.httpcomponents/httpcore-nio/4.4.1/org/apache/http/nio/pool/AbstractNIOConnPool.java/#382

I'll provide more details as I investigate.
