> Key: QPID-6451
> URL: https://issues.apache.org/jira/browse/QPID-6451
> Project: Qpid
> Issue Type: Bug
> Components: Java Client
> Affects Versions: 0.32
> Reporter: Keith Wall
> Assignee: Alex Rudyy
> Priority: Minor
> Fix For: 6.0 [Java]
>
>
> Since QPID-6350, the Java Client 0-10 has been logging ConnectionExceptions at SLF4J error. Unfortunately this change also causes ProtocolVersionException (and RedirectConnectionException) to be logged too. These exceptions don't represent true error conditions, so logging them at error is inappropriate.
> Whilst this change does not cause a functional issue, it has the potential to confuse users and can unnecessarily pollute logs.
