I have trouble with TransportSerializationException that occurs within our maven junit test case. All the servers and clients have been recently upgraded to ES 1.0.0 and has identical version of JAVA 7. The unit test cases worked with out any problem before and it still works in our Eclipse IDE environment. It simply fails during our maven build test stage. Here is our log.
