------------------------------------------
Summary: Shaded concurrentlinkedhashmap-lru conflicts with
existing jar
Key: CAMEL-5342
URL: https://issues.apache.org/jira/browse/CAMEL-5342
Project: Camel
Issue Type: Bug
Components: camel-core
Affects Versions: 2.9.2
Reporter: Mikhail Moussikhine
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.
