"To view this web content you need to install Java Runtime Environment" - Anyone know how to fix this?

Thanks LucyFerarum, you put me on to the right trail to get this fixed finally. All these other posts instructing to install and old Java library are not correct, nor is installing the JDK really fixing the issue. The com.facebook.videochat.* was also the offending startup process causing the issue for me.

Here are the steps I had to do, as even after removal it kept returning on reboot:

  1. Open a Terminal Prompt
  2. Show non Apple startup Agents. At $ execute "launchctl list | grep -v apple", will look something like the following. PID Status Label
  3. 0 org.openbsd.ssh-agent 282 0 com.symantec.symsecondarylaunch.application 274 0 com.symantec.quickmenu.application
  4. 0 com.google.keystone.system.agent
  5. 0 com.valvesoftware.steamclean
  6. 0 com.oracle.java.Java-Updater 276 0 com.Logitech.Control Center.Daemon 302 0 com.google.Chrome.62228
  7. 1 com.facebook.videochat.Chad.updater 295 0 com.symantec.scannotification.application
  8. 0 net.tunnelblick.tunnelblick.LaunchAtLogin 275 0 com.symantec.savdiskmountnotify.application 317 0 net.tunnelblick.tunnelblick.119880 One of the returned items is likely your issue, mine was "com.facebook.videochat.USERNAME.updater"

  9. Change to the Agents directory, "cd ~/Library/LaunchAgents/"

  10. I also had to remove the actual agent, as it kept re-appearing on reboot. You can view those on your system and remove. List out the items in directory "ls" com.apple.CSConfigDotMacCert-lingmann@me.com-SharedServices.Agent.plist com.facebook.videochat.USERNAME.plist com.valvesoftware.steamclean.plist net.tunnelblick.tunnelblick.LaunchAtLogin.plist org.virtualbox.vboxwebsrv.plist

  11. From ~/Library/LaunchAgents/ execute "rm com.facebook.videochat.USERNAME.plist"

  12. Do remove from Launch control with "launchctl remove com.facebook.videochat.USERNAME.updater"

  13. Exit and reboot

Hope this helps someone else, this has been and extremely annoying issue.
