      Description

      Trying to run the docs example in pipeline script fails:

      def s = 'The 3 quick\nbrown 4 fox'
      def result = ''
      new StringReader(s).splitEachLine(/\d/){ parts ->
          result += "${parts[0]}_${parts[1]}|"
      }
      assert result == 'The _ quick|brown _ fox|'

      This results in

      hudson.remoting.ProxyException: Assertion failed: 
      
      assert result == 'The _ quick|brown _ fox|'
