Huge resident size despite small heap

[Stefan Reich]

Thanks everyone for your help. It seems the process is running stable now
using JDK 18. (Resident size 1.6 GB with 400 MB live Java objects.)

Bit of an anticlimactic ending to the mystery (was there a bug that got
fixed since JDK 16?), but as things are fine, I won't complain.
