Can't start server, vanilla or forge

I’ve tried downloading the latest of both SpongeVanilla and SpongeForge. I followed the latest directions, but I get the following crash report:

`---- Minecraft Crash Report ----

You’re using an old JRE version, Sponge requires 1.8.0_40 and above (latest is always recommended)

I have updated JRE, and it shows as 1.8.0_66 in the SystemPreferences, but the crashlog still says 1.8.0_05. I restarted everything.

Hmm well perhaps the old installation is still there, you could try uninstalling it first. could also be that you have a JAVA_HOME environment variable pointing to the old location, or the PATH variable is not updated.

Thanks for your help. Turns out you have to update JDK, NOT JRE to get the right result in Terminal.
