Discouraged Access using jBPM

I am new to JBoss AS and jBPM. I installed the jBPM demo (v5.4) using AS v7 and Eclipse. When I open the demo and look at ProcessTest.java, I have the following warning on several lines:

Discouraged access: The type HornetQHTWorkItemHandler is not accessible due to restriction on required library D:\droolsjbpm\jbpm-installer\runtime
\jbpm-human-task-hornetq-5.4.0.Final.jar

That file exists (I am runing in Windows), and it has read access, so what do I need to do to fix this? The demo currently won't run properly. Thanks!
