I’ve just upgraded IntelliJ to the latest version. When I run it, editor windows and tool panels do not appear. No errors are reported. I just cannot open tool and editor windows. I cannot work at all! I’ve tried restarting it, deleting and reinstalling it, restarting the Mac, deleting workspace.xml in my project. I just can’t get it to work.

What can I do?

Where does it report errors?

I’ve paid for the subscription at the max level, and the damn thing just doesn’t work.

The previous version doesn’t work either. So it must have corrupted some files on the disk somewhere. But what? How do I find out?

Haskell plugin?

natpryce

04/26/2017, 12:43 PM

But how can a plugin put the entire IDE into an invalid state like this?

yole

04/26/2017, 12:43 PM

unfortunately it can

natpryce

04/26/2017, 12:43 PM

Seems like a deeper bug in the plugin loader

natpryce

04/26/2017, 12:44 PM

Uninstalling the Haskell plugin fixed it!

natpryce

Thanks.

I’ll keep a note of the location of the log file for future reference.

as for a plugin breaking the IDE, it's possible to add handlers for specific cases when such problems arise, and we've added quite a few over the years, but there is no general solution. there is simply no isolation between the classes of IDEA and a plugin

natpryce

04/26/2017, 12:46 PM

Is work being done to rubustify the plugin mechanism, to protect core IDE functions from misbehaving plugins?

if you can file an issue in IDEA project with a full stacktrace, we'll likely be able to add a handler for your case

Will do
