I couldn't get the Apache Commons Pool libary to load under Karaf so I
tried rewriting the app to use BoneCP instead of HikariCP. Bone doesn't
have this dependency.
This appears to work. BoneCP does want to load. Unfortunately I also
have a Redis database which also has the dependency on Apache Commons
Pool. So I'm back to the same error just one line down in my code.
It doesn't look like there are any alternative connection pool libraries
for Redis.
I want to be able to connect to my Redis db using a connection pool,
anyone know how to do that?
