Doc Text:	The camel-jbossdatagrid component requires embedded cache dependencies when a remote cache is used. The required dependency is infinispan-embedded.jar as well as the expected infinispan-remote.jar. There's the same problem when using only an embedded cache. The infinispan-remote.jar dependency is required in this case together with infinispan-embedded.jar. There's currently no workaround for this issue.	Story Points:	---

Description Martin Gencur 2015-04-30 13:06:26 UTC

The logic of camel-jbossdatagrid component requires a dependency on infinispan-embedded/infinispan-core in all cases, even if just a remote cache is used. 

There should be separate sets of dependencies for both use cases - remote cache and embedded cache.

Comment 4 Martin Gencur 2015-05-12 10:39:49 UTC

I've checked the current solution and the separation of dependencies is not complete yet. I'm getting the following exception when using an embedded cache:

	at org.apache.camel.support.ServiceSupport.start(ServiceSupport.java:61)

When I look at the code, there are still places where both infinispan-remote and infinispan-embedded are needed. E.g. InfinispanAsyncClusteredEventListener where both @Listener and @ClientListener are used on the same listener class.
