JPA error with Jdev 11g and 3.6 server

Question

I am testing a sample JPA demo I found on OTN and I am running into an issue when I start a coherence instance in a command window and run the sample code within jdev. If I run this example in Jdev with out starting the extra instance it will run correctly. The error I get is shown below, ideas???
