Sure it's:
eclipse.ini:
-startup
plugins/org.eclipse.equinox.launcher_1.0.201.R35x_v20090715.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.gtk.linux.x86_64_1.0.200.v20090519
-product
org.eclipse.epp.package.jee.product
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
256m
-vmargs
-Dosgi.requiredJavaVersion=1.6
-XX:MaxPermSize=512m
-Xms128m
-Xmx512m
eclipse.sh: (used to start Eclipse)
#!/bin/sh
export PATH=/opt/jdk1.6.0_18/bin/:$PATH
export GDK_NATIVE_WINDOWS=1
/home/some.user/eclipse35/eclipse/eclipse -clean
A few things were being tried, like setting requiredJavaVersion to 1.5 and setting MaxPermSize to 256m.
