John Blum commented on GEODE-7201:
----------------------------------
This does not only affect Spring! This is easy enough to reproduce without
Spring, by simply using the Apache Geode API.
> Useless and unhelpful Exception inappropriately logged at ERROR

> Key: GEODE-7201

> Project: Geode
> Issue Type: Bug
> Reporter: John Blum
> Priority: Major
> Labels: affects-spring

> For testing, it is valid that I might register interests on a client Region
> where the server-side Region is a PARTITION Region, yet I am not using either
> mcast-port or Locators since I only need a single server for my tests!
> Therefore this Exception is not helpful in anyway and only adds confusion to
> the user...
> {code}
> 08:59:51 Caused by: java.lang.IllegalStateException: Should not register
> interest for a partitioned region when mcast-port is 0 and no locator is
> present

> So, I "should" not...

> Why not?
> And, why does this message need to be logged at ERROR? WARN would suffice,
> especially since "_should_" implies a "_recommendation_" and not a strict,
> hard rule or requirement, which would rather be appropriately stated as
> "_Must not register interest..._".
