Add the required libraries to the classpath for commons-pool v2.0

The Apache Commons Pool open source software library provides an object-pooling API and a number of object pool implementations. Version 2 of Apache Commons Pool contains a completely re-written pooling implementation compared to the 1.x series. In addition to performance and scalability improvements, version 2 includes robust instance tracking and pool monitoring.

Version 2.7.x and up requires Java 8 or above. Version 2.6.x requires Java 7 or above. Version 2.5.x requires Java 7 or above. Version 2.0 requires 6 or above.
