Not seeing BoneCP shutdown() with Hibernate, Spring, Bonecp - spring

Question

I am implementing an application with Spring, Hibernate and BoneCP. When I invoke the shutdown script of Tomcat I see errors like this
The web application [/REST] appears to have started a thread named [BoneCP-release-thread-helper-thread] but has failed to stop it. This is very likely to create a memory leak.
When i see my logs, I am not seeing "Shutting down connection pool...", so I am assuming I am missing something over here.

This is a known issue. See https://code.google.com/p/guava-libraries/issues/detail?id=92.
Try using the snapshot version of bonecp-0.8.0-rc2 which contains 14.0.1 version of guava that has fixes for guava Finalizer thread not closed.
You can grab the snapshot from here -> https://oss.sonatype.org/content/repositories/snapshots/com/jolbox/bonecp/0.8.0-rc2-SNAPSHOT/
