Author of this post fails to take in account the link he highlighted was only posted a day ago on 4/2/2104. It could have been very likely that the documentation to enable Java 8 support in Eclipse was lacking up until only recently, and although the referenced post where the guy switched to Netbeans was posted today the trouble he was undertaking happened 4 days after the release of Java 8, which would have been a couple weeks ago.
If anyone can figure out how to look stuff up from the future please let me know though, I can conjure up a few useful applications for such an ability just off the top of my head.
