  Marking an LTS candidate under the assumption that this is fixing a regression introduced in 1.607 by the fix of JENKINS-27565, though that is not clear to me.

  It does not fix a regression introduced in 1.607, rather I spotted the stack trace while testing (I cannot recall whether on pre 1.607 or post 1.607 testing) and analysis revealed the potential of a div by zero, so might as well fix.
  
  No harm in backporting to LTS anyway
