GEODE-2823: The listener now forces a copy of the value to be made
> The LuceneEventListener caues deserialized values to be stored in the entry
> when the region contains DataSerializable or Serializable values

> Key: GEODE-2823
> URL: https://issues.apache.org/jira/browse/GEODE-2823
> Project: Geode
> Issue Type: Bug
> Components: lucene
> Reporter: Barry Oglesby
>
> If the {{Region}} contains {{DataSerializable}} or {{Serializable}} values,
> then each {{RegionEntry}} contains a {{VMCachedDeserializable}}. When
> {{LuceneEventListener.process}} calls {{entry.getValue()}}, the value is
> deserialized and left in that state in the {{VMCachedDeserializable}}.
> Below is a live histogram for the no index test.
