I'm trying to update Java on my MacBook (OS X 10.9.5). When I download the most resent version (v8 update 40) from java.com and try to install it, it pops up an error box saying
You are trying to install 22.214.171.124, however 14.9.0 is already installed
and that's it. In a terminal I get
java -version java version "1.6.0_65" Java(TM) SE Runtime Environment (build 1.6.0_65-b14-462-11M4609) Java HotSpot(TM) 64-Bit Server VM (build 20.65-b04-462, mixed mode)
But Firefox → Tools → Add-ons shows Java 14.9.0 (and says it's outdated), though there is no option to de-install it.
So, how can I install the most recent Java 8.40? How can I uninstall this mysterious Java 14.9.0?
