---------------------------------------
Summary: ConcurrentModificationException in shutdown due to
passing a collection to logger
Key: GEODE-6359
URL: https://issues.apache.org/jira/browse/GEODE-6359
Project: Geode
Issue Type: Bug
Reporter: Galen O'Sullivan
This occurred in a PR build, but appears unrelated from the changed code. It
seems to be due to passing a collection into a logger, and that collection
being modified while the logger is logging it.
