Hey Achim,
right now I have one bundle that contains the Redis client classes
themselves but not the Apache Commons Pool classes. (I haven't figured
out how to install jedis as a separate bundle from maven yet, errors...)
Those classes are loaded using the import statement in the manifest:
Import-Package: org.osgi.framework, javax.naming, org.slf4j, javax.sql
, javax.management, sun.net, org.apache.commons.pool2.proxy, org.apac
he.commons.pool2.impl, org.apache.commons.pool2, com.mysql.jdbc,
com.jolbox.bonecp, com.google.common.base,
com.mysql.jdbc.jdbc2.optional
my list of installed bundles is as follows:
karaf@root()> list
START LEVEL 100 , List Threshold: 50
ID | State | Lvl | Version | Name

So my imports list all the packages that are exported by the Apache
Commons Pool library. Those packages also include the class that I'm
getting the load error for.
