That is a terrible idea. The JVM basically never returns RAM to the OS, and in my experience, if you run a java process long enough, the max heap size ends up being the used heap size.

G1 the default allocator returns heap to the os only when you set -G1PeriodicGCInterval and both ZGC and Shenandoah do it automatically.
