[jira] [Commented] (CAMEL-5342) Shaded concurrentlinkedhashmap-lru conflicts with existing jar

    [ https://issues.apache.org/jira/browse/CAMEL-5342?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13291549#comment-13291549 ] 

Ben Manes commented on CAMEL-5342:
----------------------------------

CLHM v1.3 includes an OSGi manifest, if that helps.

> Package com.googlecode.concurrentlinkedhashmap:concurrentlinkedhashmap-lru is included/shaded inside the camel-core jar.
> It is not very nice if concurrentlinkedhashmap-lru.jar is already on the path. It is a deal breaker, if their versions are different. For example cassandra-1.1.1 requires ConcurrentLinkedHashMap$Builder.maximumWeightedCapacity(), which is missing from the version included in camel.
> It would be nice if concurrentlinkedhashmap-lru was included as a normal dependency. Comment in the pom.xml says "Shade the googlecode stuff for OSGi". Well, if that is strictly required, maybe it could be better included in camel-core-osgi package.
> In any case, if it must be shaded at all, it would be safer to use relocation property of the maven-shade-plugin. In this case, camel could stay with the version it wants, without conflicting with explicit dependencies.
