PropertyAccessException trying to deploy ProcessDefinition

[chipschoch]

JBossAS 4.2.2 JBM 3.3.0.GA

I am trying to deploy a ProcessDefinition from within my code and I get a PropertyAccessException.

ProcessDefinition processDefinition = ProcessDefinition.parseParZipInputStream (zis);
 jbpmContext.deployProcessDefinition (processDefinition);

I get:
