Issue Description

When I visit 'http://localhost:9000/train/overview' after running UIExample, it returned 'Internal Server Error' and the following error. Is there something wrong?

java.lang.NoSuchMethodError: org.apache.commons.io.IOUtils.readLines(Ljava/io/InputStream;Ljava/nio/charset/Charset;)Ljava/util/List;
