Within that 8000+ lines log file, I guess this could be the initial culprit:

If I read this correctly, something is trying to activate emf.core. During that course, something needs the instance location to be initialized, but it is not, so class loading aborts, with the typical mayhem following.

Ed, is this among the things that have been fixed in 4.15 (perhaps in Platform)?

BTW, towards the bottom I found this

!MESSAGE Software being installed: EMF RAP Target Components 2.20.0.v20190920-0401 (org.eclipse.emf.rap.sdk.feature.group 2.20.0.v20190920-0401)

Isn't this strictly incompatible with the IDE?

I don't know if they fix the bugs in 4.15.

It supposed to be compatible since it downloaded from the ver 2019.12 bundle. It shows v20190920 so they loaded by mistake.

Comment 5 John smith

2020-03-10 12:12:33 EDT

So, I should remove all the plug-in which are for v20190920 from the install menu.
Is that will fix the problem?

My question was directed to Ed Merks, who I'm sure understands what I meant.

It's not the date that raised my suspicion, but RAP as a runtime is not meant for the web, not for the desktop. But admittedly I don't know what's in "EMF RAP Target Components".

Comment 7 Ed Merks

2020-03-10 13:04:07 EDT

There's no description of how one gets into this state.  Most certainly you can't install EMF's RAP support in and IDE.
