hi,

I wonder if there are any recommended parameters for GC in Java 11? G1? And are the default parameters for that GC enough, or should they be tweaked? What about NewRatio?

I had previously CMS parameters, but as of Java 11, that is deprecated. For some reason, I could not find advice for this. UseParNewGC seems to produce errors for long GC intervals.
