KafkaStreamsTestManual.testSimple() fails with no local zk or kafka servers

I have set up a kafka on local and a remote machine following the quick start guide http://kafka.apache.org/quickstart. And I pulled the latest code of the branch "release1.0.0". I tried to run KafkaStreamsTestManual.testSimple(), but found it works with local kafka but fails with the remote kafka (the error shown as below ). I have tested my remote kafka with my local kafka console client and the SimpleSubscriberApp.java so I am sure that it works. And I even tried to start local kafka consumer console client during testSimple() is running, I can get the messages ('Hello' and 'Are you there?') from the console. So I am suspecting that there is something wrong with Edgent Tester to handle this test case.
