Cache Component needs to check for null values during GET operations
--------------------------------------------------------------------
Key: CAMEL-3077
URL: https://issues.apache.org/activemq/browse/CAMEL-3077
Project: Apache Camel
Issue Type: Bug
Affects Versions: 2.4.0
Environment: Received 2.4.0 release of Camel and Camel Cache component
from Maven repo
Reporter: John Ellis
Attachments: CacheProducer.NPE.patch
EhCache often has a bit of lag time when invalidating expired cache elements,
first setting the Element value to null and then removing the key. If you are
hitting a cache rapidly one often will run across a key that is present in the
cache that still has a null element entry.
The logic for successfully key retrieval just needs to be slightly tweaked to
check for null values.
