We are running Ready API scripts in Container based environement.  While building and running our docker image, we are getting an Java error during the License acquiring

The issue exist in both build and run time. During the run time a new user ? getting created during docker run

 

During Docker build

Step 26 : RUN echo "1" | java -jar /readyapi/licensing/ready-api-license-manager-1.2.6.jar -s ${ls_address}:1099 -f /home/soapui/.soapui/soapui.key
---> Running in 6565fc8aeaed
May 28, 2019 1:45:14 PM java.util.prefs.FileSystemPreferences$1 run
INFO: Created user preferences directory.

 

During Docker run:

Same error occurs and after the error it creates a user name called ?

My docker run fails as it is unable to find the license whic ofcourse will not be present in user called ?

 

Any Idea what could be the reason for creating a ? user
