I created a PR to remove the part that seems to be JVM specific from the expected test output. What JVM version are you running on Ubuntu? To make sure we have no JVM-specific dependencies we should run CI against a setup similar to what you use.

openjdk version "10.0.1" 2018-04-17 OpenJDK Runtime Environment (build 10.0.1+10-Ubuntu-3ubuntu1) OpenJDK 64-Bit Server VM (build 10.0.1+10-Ubuntu-3ubuntu1, mixed mode)

We currently do not support JDK versions other than JDK 8. I think that might have caused the errors you saw

You re right , i deleted the version 10 and re-installed the JDK 8. and now the mvn clean install success for the first time :
