ExceptionInInitializerError

SoapUI 4.5.1
Eclipse Juno
JDK 1.6
Win 7SP1, 64b
JUnit 4.10

I can run the SoapUI app but I'm getting an error when I set up to run the mock inside of a JUnit test method. See stack trace below.

I have set the build path so that it includes the soapui jar and has the SOAPUI_HOME/lib dir listed as an external class folder as well as setting all of the jars in the lib dir as external jars.

Any ideas?
