Occupancy is computed as ((capacity - used) / capacity), see src/jdk.jcmd/share/classes/sun/tools/jstat/resources/jstat_options, search for "gcutil". G1, ZGC, and Shenandoah may return zero capacity for any or all of survivor spaces, eden, old gen, metaspace, and compressed class space, leading to an occupancy result represented by '-'.
