---------------------------------------
Summary: Client throws ToDataException when locator is shutting
down
Key: GEODE-5646
URL: https://issues.apache.org/jira/browse/GEODE-5646
Project: Geode
Issue Type: Bug
Components: client/server
Reporter: Bruce Schuchardt
This hasn't been seen in Geode but in an older version of Pivotal GemFire. The
code in question hasn't changed so we ought to fix it.

The client is trying to serialize ServerLocation objects and send them to a
locator. AutoConnectionSourceImpl.queryOneLocator() has code to handle
IOException and report the locator as being down but since ServerLocation isn't
a DataSerializableFixedID instance the serialization code throws a
ToDataException instead of an IOException. Adding ToDataException handling to
queryOneLocator() should fix the problem.
