It's been the default GC since Java 9 https://en.wikipedia.org/wiki/Garbage-first_collector

Ah, I'm confusing its availability with Shenandoah and zgc.

Unfortunately, the last time I used IntelliiJ it came with its own JDK8. Is that still the case, I wonder?

I just ran an update, IDEA and PyCharm use OpenJDK 11, Android Studio still uses 1.8.
