I/O reactor (client) terminates abnormally when a connection is prematurely
closed probably because of timeout settings. A NullpointerException is thrown
when a response is being read and the connection is already closed and set to
null

Key: HTTPASYNC-6
URL: https://issues.apache.org/jira/browse/HTTPASYNC-6
Project: HttpComponents HttpAsyncClient
Issue Type: Bug
Affects Versions: 4.0-alpha2
Environment: Windows Vista , Sun Java SDK 1.6.0_26
Reporter: Menno van Gangelen
Priority: Critical
The following line should have a check for null.
org.apache.http.impl.nio.client.DefaultAsyncRequestDirector.responseCompleted(DefaultAsyncRequestDirector.java:366);
=> if (this.managedConn.isOpen()) {
Hard to reproduce as it seems to be a racing issue when reading from slow
websites.
