JDK 27 G1/Parallel/Serial GC Changes

> selecting something else depending on arcane environmental conditions was more of a burden than an advantage

What is being referred to here? Does "else" refer to ZGC, Shenandoah?

What does arcane env conditions mean?

Are people still dealing with GC issues?

I find that it basically just more or less works out of the box on modern JVMs.

GC's haven't freed us from manual memory management, you just do all that manual work with environment variables, or making sure to "pick the right collector for the job", or debugging performance or heap size issues, or chasing down weak references or confused finalizers.
