Eclipse VM version

[ghost]

This issue could be a platform issue but the -vm argument is not set like it should according to this:
https://wiki.eclipse.org/Eclipse.ini

I am using Eclipse Luna on MacOS X Yosemite with Java 1.6 and 1.8 installed.

After I installed 1.8 I assumed Eclipse will use it but I might be wrong as this is not set in eclipse.ini.

The -vm argument reads like this: -vmargs

And on the line below I can read this: -Dosgi.requiredJavaVersion=1.6

So it might be using Java 1.6 - how do I know?

Is it not possible to select a VM from Eclipse preferences instead of hacking eclipse.ini?

There are millions of Eclipse users, and this is very basic feature, there is hardly a bug.

What is your full eclipse.ini content?

As for -Dosgi.requiredJavaVersion=1.6 it is OSGI stuff, and not about what JDK to use

Have you read https://wiki.eclipse.org/Eclipse.ini ?

add 2 lines before -vmargs

like

 -vm
/System/Library/Frameworks/JavaVM.framework/Versions/1.6.0/Home/bin/java

Reading you I understood the VM version Eclipse was using was actually specified in eclipse.ini so I looked to make sure the changes I made at system level to use 1.8 were visible in there but they are not.

Now I understand the -vm argument could be used only to select a different VM - but I don't need that...

you need something like https://github.com/Nodeclipse/nodeclipse-1/blob/master/org.nodeclipse.enide.maven/.settings/org.eclipse.jdt.core.prefs
