ClassNotFoundException While ShuttingDown Apache Felix Using H2

[xipki]

Environment

HikariCP version: 2.6.2
JDK version     : 1.8.0_121
Database        : H2
Driver version  : 1.4.196

I got the same error as #298, even the DataSource is closed explicty. I use apache karaf 4.0.9, HikariCP 2.6.2 and H2 database 1.4.196. The maven project to reproduce the bug is attached.

The steps to reproduce the bug are as follows (hikaricp-h2-bug*.jar will be generated contained in the attached file):

1. Unzip the attached zip-file, and then
   mvn clean install
2. Download the apache-karaf from https://repository.apache.org/content/groups/public/org/apache/karaf/apache-karaf/4.0.9/apache-karaf-4.0.9.tar.gz
3. Unzip the tgz-file
4. Start the karaf
   bin/karaf
5. In the karaf console, execute the following commands:

   karaf@root()> karaf@root()> install mvn:com.h2database/h2/1.4.196

@xipki Thanks for the zip, but I don't have a Karaf installation, so it doesn't help that much.

@brettwooldridge Thanks for excellent project. I updated the issue description.
