      Steps to reproduce

      Create a freestyle job, then stop Jenkins.

      Add leading line breaks to the job's config.xml, like so:

      <?xml version='1.0' encoding='UTF-8'?>
      <project>
        <keepDependencies>false</keepDependencies>
        <properties/>
        <scm class="hudson.scm.NullSCM"/>
        <canRoam>false</canRoam>
        <disabled>false</disabled>
        <blockBuildWhenDownstreamBuilding>false</blockBuildWhenDownstreamBuilding>
        <blockBuildWhenUpstreamBuilding>false</blockBuildWhenUpstreamBuilding>
        <triggers/>
        <concurrentBuild>false</concurrentBuild>
        <builders/>
        <publishers/>
        <buildWrappers/>
      </project>
      

      Start Jenkins
