Problem Ubuntu 16.04.2
According to /etc/issue I’m running 16.04.02. I don’t recall if I did a clean install or updated an earlier 16.04 release. Ordinarily I just upgrade for point releases (and major releases where possible.)
Java reports as
hbarta@olive:~$ java -version
openjdk version “1.8.0_121”
OpenJDK Runtime Environment (build 1.8.0_121-8u121-b13-0ubuntu1.16.04.2-b13)
OpenJDK 64-Bit Server VM (build 25.121-b13, mixed mode)
hbarta@olive:~$
I’m running eclipse Neon (Neon.2 Release (4.6.2))
Did you remember to install other dependencies? Thet’s where I usually mess up following a new install. There is the need to install some 32 bit libraries IIRC (and you may need to add that architecture.)
Dod you try running Eclipse from the command line to see if it puts out any useful diagnostics?
(Apologies for any typos. The forum S/W seems to have defeated the spell checker built into Chrome.)
