JUnit testing blueprint with openJPA in route - apache-camel

Question

I have a test case that loads up the blueprint.xml and persistence.xml at the start of the JUnit but when the test actually runs an error is thrown for not having a persistence provider.
Caused by: javax.persistence.PersistenceException: No Persistence provider for EntityManager named blacklisting-pu
at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:69)
at org.springframework.orm.jpa.LocalEntityManagerFactoryBean.createNativeEntityManagerFactory(LocalEntityManagerFactoryBean.java:92)

at org.apache.camel.component.jpa.JpaEndpoint.createProducer(JpaEndpoint.java:103)
at org.apache.camel.impl.ProducerCache.doGetProducer(ProducerCache.java:405)
here is the first part of the log showing the provider is loaded:
16 blacklisting-pu TRACE [main] openjpa.Runtime - Setting the following properties from "file:/workspace/git/jdbc-util/target/test-classes/META-INF/persistence.xml" into configuration: {openjpa.jdbc.SynchronizeMappings=buildSchema(SchemaAction='add,deleteTableContents'), openjpa.ConnectionPassword=, openjpa.ConnectionDriverName=org.h2.Driver, javax.persistence.provider=org.apache.openjpa.persistence.PersistenceProviderImpl, openjpa.MetaDataFactory=jpa(Types=com.entity.MyEntity), openjpa.Log=DefaultLevel=TRACE, Tool=INFO, PersistenceVersion=1.0, openjpa.ConnectionUserName=, openjpa.ConnectionURL=jdbc:h2:mem:blacklisting;DB_CLOSE_DELAY=1000, openjpa.Id=blacklisting-pu}

I had the test case working using spring and defining the route in a spring camel-context.xml but then I needed to move the route to a blueprint.xml and now it can't seem to find the persistence.xml at runtime for the tests.
I have been using this as my reference along with alot of googleing:
http://camel.apache.org/blueprint-testing.html
Any help would be much appreciated
EDIT:
I have ran the following as part of the setup method in JUnit and the calss is found without issue
Object obj = Class.forName("org.apache.openjpa.persistence.PersistenceProviderImpl").newInstance();
if(null==obj){
Assert.fail("org.apache.openjpa.persistence.PersistenceProviderImpl not present on classpath.");
}else{
LOG.info("the class {} exists on the calsspath.",obj.getClass().getName());
}
here is the log showing it loaded

the class org.apache.openjpa.persistence.PersistenceProviderImpl exists on the calsspath.
