Expected Behavior

JRuby 9.2.6 works fine in Linux, thanks for this great software. However we get the attached error during startup. What are we doing wrong?

• Describe your expectation of how JRuby should behave, perhaps by showing how CRuby/MRI behaves.
  Just not print that error :)

• Provide an executable Ruby script or a link to an example repository.

Actual Behavior

/home/osboxes/Applications/jruby-9.2.6.0/bin/jruby.sh /home/osboxes/Documents/workspaceRuby/kubarails/bin/rails server -b 0.0.0.0 -p 3000 -e development

Thanks in advance.
