This still (or again?) happens in 7002. Now it even said that it's going to deadlock ;)

We are getting continuing issues with this and our inspections. Are you having trouble reproducing this? In case you are, and I am not surprised, since it took me a while to make a crashing combination, I am attaching a sample project which crashes, the log file, and our inspections profile which is causing the crash.

I also noticed that it doesn't crash as long as you do not make our inspections the project default, you just run the inspections in the Inspect Code option.

Please tell me if you can reproduce this your end with my files, because if not, I will do more work to make sure you can.

Thanks!

Project, log and inspections which reproduce this bug, as described in my other comment.

Okay, we think we now have this nailed!

The inspection that is causing this problem is the "Redundant suppression" inspection. If you have that turned on, with some suppressed inspections, AND you have that modified IDE inspection profile set as your default it crashes on Analyse / Inspect Code. If you have the project default set as the default, but choose the modified inspection profile to run under Analyse / Inspect Code, it works fine.
