-----------------------------------
Summary: Camel-AHC-WS: reconnect exception is not passed to
exception handler
Key: CAMEL-12951
URL: https://issues.apache.org/jira/browse/CAMEL-12951
Project: Camel
Issue Type: Bug
Components: camel-ahc-ws
Affects Versions: 2.22.2
Reporter: Jukka Aalto
When WsEndPoint reconnect-method fails in line 172 to create connection it
throws an exception which is logged but it should also be given to exception
handler.
This kind of situation happens when server is shut down while connection is
open. First client tries to reconnect but when reconnect fails, client stops
trying.
I'm trying to implement a feature which tries continuously to reconnect to
server when the server is down. Connection state (open, disconnected or trying
to connect) should also be indicated.
If exception is passed to exception handler then it would be possible to
register exception handler outside Camel. The purpose of this exception handler
is to shut down Camel context and recreate it again in order to reconnect. With
this kind of setup I can continuously try to reconnect and also figure out the
current connection state.
