Hi,

Shenandoah does provide similar functionality under experimental flags:
-XX:+ShenandoahUncommit
-XX:ShenandoahUncommitDelay
It does not need full gc before uncommitting (actually it calls
madvise(MADV_DONTNEED) on Linux)
Also, it has "compact" heuristics that targets low memory footprint by
aggressively uncommitting heap.
