Java, Run Time or Oracle?

[Rod]

I upgraded my wife's computer to Yosemite two days ago and apart from an odd hiccup with Mail everything is fine, however. On initial restart a dialogue box popped up stating that Java Run Time was required for some internet content. This did not happen with my identical MBP after upgrade. The box included a link to the developers' site so my wife downloaded the installer and ran it. Made no difference. Box still popped up on startup and periodically during use. A little reading on my part found there was another Mac version called Oracle Java. So I downloaded the zip ran the installer and now no more popup dialogue. So I am curious why I didn't get the same notification and why there are two seemingly appropriate types of Java for the Apple OS.

I don't know other than she has other applications that you don't, or the upgrade was done differently.

What I do know is all the various versions and bits and pieces of Java is a confusing mess.

As for the Java Runtime she needed, have a look at Adobe's page:

I was trying to investigate a bunch of java stuff the other day and I got completely confused, except I did manage to get a site working again that their latest security version update wasn't "authorized" and I had to create an exception rule to allow me access. I bit of a PITA as they don't make it easy at all.
