  Discovered during Java 10+ hackathon. To reproduce:
  
  	
  Run Jenkins with Docker Java 10 image: docker run -p 8080:8080 -p 50000:50000 jenkins/jenkins-experimental:blueocean-jdk10
  	
  Setup and unlock Jenkins at http://localhost:8080
  	
  Click 'Install suggested plugins'. All plugins configure except Email extension. 
  	
  Attempt a retry and this still fails.

  Java 10 is obsolete and won't ever be supported with Jenkins.
  
  Java 11 and the e-mail extension plugin work great with Java 11.
