Attempting to update HAPI from 0.5 to 2.0 via an OMRS module results in a ClassCastException exception

I'm trying to use OpenMRS 1.9.0 (which uses HAPI version 0.5), and upgrade this to HAPI 2.0 via a module.
For this, i'm introducing the dependency

<dependency>
<groupId>ca.uhn.hapi</groupId>
<artifactId>hapi-base</artifactId>
<version>2.0</version>

to the module pom.xml, so that the newer version of the module will be loaded into OpenMRS. However, when I try to start this module using OpenMRS 190, the following exception is thrown,
