This problem is still unresolved....
Coming late to this party, and I don't really have a good theory about why this might be happening, but I wonder if removing all Java installations - JRE's, JDK's - and scrubbing the OS of all references to them, might help.
Unless the user is using some
other application that uses Java, there's no reason to have them on the machine. Other apps would be NetBeans, or some of the functions of LibreOffice Base, for example. There aren't a lot of desktop Java applications out there.
