Pranav Arora created HTTPCORE-587:
-------------------------------------
Summary: Connection must be created by connection manager issue
Key: HTTPCORE-587
URL: https://issues.apache.org/jira/browse/HTTPCORE-587
Project: HttpComponents HttpCore
Issue Type: Bug
Components: HttpCore, HttpCore NIO
Affects Versions: 4.4.11
Reporter: Pranav Arora
This is the same issue that is discussed in HTTPCORE-370 and HTTPCORE-574. I am
facing the following exception:
{code:java}
[ERROR] [] 2019-07-29 09:33:10.639 [pool-2-thread-1] InternalHttpAsyncClient -

This occurs randomly during production and I have not been able to reproduce it
locally. What I instead tried was pass a custom exception handler.
{code:java}
public class CustomExceptionHandler implements IOReactorExceptionHandler {
@Override
public boolean handle(IOException ex) {
log.error("I/O Reactor IO exception", ex);
return false;
}
@Override
public boolean handle(RuntimeException ex) {
log.error("I/O Reactor Runtime Exception", ex);
if (ex instanceof IllegalStateException) {
throw new CancelledKeyException();
}
return false;
}
}
{code}
It helped for the above exception as it did not lead to immediate shutdown of
I/O Reactor but now I am facing a different issue.

DefaultConnectingIOReactorTemp is exactly the same as
DefaultConnectingIOReactor with the added code that was intended to fix
HTTPCORE-370. The corresponding line in DefaultConnectingIOReactor is 167
(final SessionRequestImpl sessionRequest = requestHandle.getSessionRequest()).
