Doc Text:
When using a near cache in <literal>LAZY</literal> mode there was a possibility that a read operation following a write operation on the same key within the same thread would return outdated data. For example, the below calls from the same thread could result in <literal>v1</literal> being returned: <programlisting><![CDATA[put(k, v1) put(k, v2) get(k)]]></programlisting> This issue is resolved as of Red Hat JBoss Data Grid 6.5.1.

Description Pedro Zapata 2015-07-17 09:12:45 UTC 
Writes to the NearCache do not invalidate/update local data on put/remove operations, and so the NearCache (LAZY MODE) is invalidated using an eventlistener in an asynch way.
It is possible for a client to write a value and issue a get on the same key, and the result of the get would not be the latest value but the one which was present before the update operation.
This happens frequently when there is very much traffic on the connection of the listener which receives the events for the NearCache.
It would be better at least to invalidate locally every entry modified from the client itself
