Opening Eclipse (Mars, Java 8) today I am finding my GlasshFish Runtime missing. I am sure this is a widespread issue at this point. I have double checked that my GlassFish Tools plugin for Eclipse was installed and it still is. I have a feeling I am going to be waiting around for a fix at this point. Not a good start to trying out GlassFish for a new interop web project I am working on to interface with our archaic JDE implementation!
