Internal error occurred during: "Launching Launch Runtime Eclipse" [message #1776507]

This is a very strange issue:
Yesterday I used xtext for my project and it works fine.
Today I open the eclipse, select my xtext project, Run as Eclipse Application, then error occurred:

An internal error occurred during: "Launching Eclipse Application".
org.eclipse.jdt.launching.JavaRuntime.isModularJava(Lorg/eclipse/jdt/launching/IVMInstall;)Z
index.php/fa/31294/0/

I have no idea what cause this issue. (perhaps my environment problem?)
So I start a clean win7 snapshot image in my vmware.

1. install jdk-8u101-windows-x64.exe
2. install eclipse-java-oxygen-R-win32-x86_64
3. run eclipse and install new software for xtext
Oxygen - http://download.eclipse.org/releases/oxygen
Modeling/Xtext Complete SDK 2.120.v20170519-1412
4. Create Xtext/Xtext Project (org.xtext.example.mydsl)
Everything use defauly settings.
5. Select GenerateMyDsl.mwe2 and run it.
6. Select Project and Run as Eclipse Application
But the error still occurred....

Anyone here and encountered the same problem?
Need for help.
Very thanks.

For me it looks like you have somewhere
(Eg due automatic plugin update)
A mixture of oxygen 1a and pre oxygen 1a plugins

(Pde from 1a jdt from before)
Can you have a look at the version number of the pde and jdt plugins

org.eclipse.pde.core:
3.11.100.v20170517-0724

org.eclipse.pde.launching:
3.7.50.v20171007-1315

org.eclipse.pde.ui:
3.10.50.v20171007-1315

org.eclipse.pde.build:
3.9.300.v20170515-0912

org.eclipse.jdt:
2.13.0.v20170612-0950

the plugins org.eclipse.pde.ui and org.eclipse.pde.launching seems be automatic updated. (That is very strange, because I have turn off the automatic updates in Preferences/Install/Update/Automatic Updates)

yes. your jdt and pde are not in sync. this causes the issue

Hi

Oxygen.1a and Photon.M3 introduce both Java 9 and JUnit 5 support providing new opportunities for some obscure errors.

Many of these have been attributed to PDE(JUnit) and JDT version mismatches. It is unclear whether this is due to users or idiot distributions facilitating idiot installations.

Make very sure that you fully update from a consistent distribution and do not allow any other distribution site to contribute. Verify the "Available sites" in the Install dialog very carefully.

Thanks.
You said jdt and pde are not in sync.
But how to make it match?
Should I update jdt to a match version? or downgrade pde to a version which match jdt?
Where to find a match version?

I use eclipse-java-oxygen-R-win32-x86_64 and my available software site is default setting:

Oxygen
http://download.eclipse.org/releases/oxygen

Oxygen
http://download.eclipse.org/eclipse/updates/4.7

I dont understand why it automatic update to Oxygen.1a?
Could you give me some suggestion about how to fix this issue?
Very thanks.

Hi

I presume that you invoked Help->Check for Updates and so Oxygen.1a was provided as the best update.

org.eclipse.jdt:
2.13.0.v20170612-0950

is wrong. It should be 2.13.1... Are you sure you did not get any errors while updating? Try updating again.

In fact, I did not click Help->Check for Updates at all. As I mention at topic, I just reinstall eclipse...

Anyway, this issue was fixed, after update jdt to newest version: 3.12.1.v20171009-0410. (Only this version can be select, no 2.13.1...)

PS: But I will use neon, it more stable. oxygen seems silent update in background, even if turn off automatic update.....

Thanks again!
