I've been using the integrated java profiler on Linux in Intellij 2018.3.5. I've just upgraded to 2019.1 and the icon is now disabled. It's visible, just greyed out.
I've followed all the instruction here (https://www.jetbrains.com/help/idea/cpu-profiler.html) and rebooted but it's still disabled.
The project is a Scala project, with SBT but using Intellij for project imports and for building. Everything else works fine.
Any ideas how I can debug the problem further to see why the icon is showing up disabled?
