Description

When attempting to add an OQL Index to a Region with existing data, containing entries that have been invalidated, and when the JVM's assertion facility is enabled (i.e. java -ea ...), then Geode will throw a AssertionError:

This error seems mostly benign and when you disable Java assertions (i.e. do not include the -ea switch to the java launcher when starting the server, all is well.
