I installed JDK 1.8. When I look at Preferences > Java > Installed JREs, the only thing on the list is jdk1.8.0_60.
But when I look at Preferences > Java > Installed JREs > Execution Environments, I don't see anything above JavaSE-1.7. None of my projects can use JDK 1.8.
I've tried Googling for an answer to this, but all I get are pages that talk about how to install JDK 1.8. I've also tried reinstalling JDK 1.8 and Eclipse and that didn't work. I have no idea what could possibly be wrong.
