Did the latest stable version of IntelliJ drop support for the GTK theme?

I haven't found anything in the issue tracker so please report to https://youtrack.jetbrains.com/issues/IDEA

Turns out the GTK theme is no longer available in IntelliJ 2019.1. Still there should have been a check made by the IntelliJ updater before updating from 2018.x to 2019.x.

Ah, sorry, I search in the wrong project. The issue is https://youtrack.jetbrains.com/issue/JBR-1330
