Cannot display execution path with OpenJDK

Run bpel_simple_correlation quickstart with 'ant deploy' followed by 'ant sendhello'. Open bpel-console in firefox, and select execution path for service "

HelloGoodbye-1". I receive the following exception in the server.log.

java.lang.IncompatibleClassChangeError: Found class com.sun.image.codec.jpeg.JPEGImageEncoder, but interface was expected

That issue is discussed here [1] where the problem is that OpenJDK implements JPEGImageEncoder as a class but SunJDK implements the same as an interface.
