Fresh install of Eclipse Mars won't run

Question

Currently running Elementary OS (Ubuntu 14.04). I am able to install and run eclipse 4.4 (Luna), but after unpacking the 4.5 tar my machine crashes after the splash screen. I can't check my workspace/.metadata logs because a workspace is not created before the crash. Have tried with Java 8 from the webupd8 ppa, Java 8 from Oracle, and the openjdk-7 from the Ubuntu repos. Also tried the Eclipse installer to have the same problem, crashing after the splash screen.

Where else could I look for issues?

64 bit or 32 bit Eclipse? – Branislav Lazic Aug 14 '15 at 17:38 — Branislav Lazic, Aug 14 '15 at 17:38

GTK3 and Pantheon

Turns out the problem was with my DE (Pantheon) and GTK3 menus.

Here's the bug

So if we disable gtk3 either with:

export SWT_GTK3=0

before running eclipse or write a short script found here

#!/bin/bash
export SWT_GTK3=0
export UBUNTU_MENUPROXY=0
./eclipse -showlocation

With The GTK menus disabled, eclipse runs perfectly.

You could specify the virtual machine in the eclipse.ini file. e.g.:

-vm
/usr/lib/jvm/java-8-oracle/jre/lib/amd64/server/libjvm.so
-startup
plugins/org.eclipse.equinox.launcher_1.3.100.v20150511-1540.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.gtk.linux.x86_64_1.1.300.v20150602-1417
-product
org.eclipse.epp.package.jee.product
--launcher.defaultAction
openFile
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
256m
--launcher.defaultAction
openFile
--launcher.appendVmargs
-vmargs
-Dosgi.requiredJavaVersion=1.7
-XX:MaxPermSize=256m
-Xms256m
-Xmx2048m
-XX:+UseConcMarkSweepGC 
-XX:+CMSParallelRemarkEnabled

Tried this, specifying the java-8 Runtime. Same error occurs — Sam Pennington, Aug 14 '15 at 18:42
