Description

The issue is very much identical to CAMEL-10238 where camel component does not try to reconnect. It was resolved for that particular case, however there is additional scenario where we are facing exactly similar problem.

Here is the key log message after which component stops retrying

{{2018-05-03 17:19:50.257 WARN 7636 — [nt@911561694-23] o.a.c.c.s.i.s.SubscriptionHelper : Connect failure: {clientId=3qi3g4psrtqrntt15ockewu0a59q, advice=

{reconnect=none, interval=0}

, channel=/meta/connect, id=154, error=403::Unknown client, successful=false}}}

Please note that we are getting Connect failure multiple times but it is able to reconnect where there is exception or when the advice is to do handshake again. Here are those sample which works...

• The one with advice for new handshake

One more thing, this log is coming from line 168 LOG.warn("Connect failure: {}", message); of the https://github.com/apache/camel/blob/master/components/camel-salesforce/camel-salesforce-component/src/main/java/org/apache/camel/component/salesforce/internal/streaming/SubscriptionHelper.java#L168. I see that there is no attempt to reconnect. If this information helps move things faster...
