Starting up badly in Windows 10 [message #1838712]

Hi --

When I install Eclipse and then launch from the installer, I get a perfectly functional Eclipse.

If I terminate Eclipse and then restart using the desktop shortcut created by the installer (or executing eclipse.exe directly), for example, I find that Run | Run Configurations produces an exception creating launch configuration tabs (see attached pictures).

To get Eclipse to work properly, I have to delete it and re-install it, and launch Eclipse from the installer again.

What could be going wrong here?? Are there runtime options missing in the desktop shortcut?

(Other features break, too, but I thought I'd keep this question simple.)

Does your eclipse.ini have a -vm option in it? Is that the one that you choose to use on the second page of the installer?

There is a bug in the 2020-12 installer that the application launched from the installer is using the installer's JRE:

https://bugs.eclipse.org/bugs/show_bug.cgi?id=569513

But that should cause the opposite problem that you're seeing. I.e., the IDE launched by the installer should not work quite right. Hence the question about the -vm argument in the eclipse.ini because that's the JRE/JDK that will be used and that apparently isn't working quite right.

It might be helpful to examine the eclipse log file. This error will likely be in the log, but there may be other messages before this that might provide additional context. I also note that don't see where you indicated what Eclipse version you're installing here.

Hi, all --

Based on the kind responses by Ed Merks and David Karr, I dug a little deeper, and I think I have the culprit.

During the installation process, there was a prompt to choose the JVM ... it looks like the requirement was that I choose something that was JVM 11 or later. The default was a JRE 11 I had installed for a different application. So, I chose it. (See screenshot)

index.php/fa/40084/0/

When I wipe out my Eclipse and use the installer, but choose JRE 15.0.2, all functions work as expected.

So, I think the problem may have been my using JRE 11 instead of JRE 15.

I'm not sure whether there's a difference between the JRE 11.0.2 offered by the installer and JRE 11.0.6 I was selecting.

I think I'm quite happy, though, that Eclipse is working! (BTW, I'm on Eclipse 2020-12.)

Any comments?

Thanks for the kind and quick reply ... I think the problem is that I selected JRE11 instead of JRE15 during installation. Please see my reply to myself (once it appears). There's more information there.

If that Java 11 distribution is actually a JRE, and not a JDK, then it would fail in various ways. I imagine your Java 15 JRE Is actually a JDK, as that worked. Eclipse needs a JDK.

I think that's exactly right ... the JRE was needed/installed for Cytoscape, which doesn't require a JDK.

This might explain a lot of what I saw ... like failure of Eclipse's debug-oriented packages to load.

This is very good news. Thanks!
