| ShenandoahGCHeuristics | string | GC heuristics to use. This fine-tunes the GC mode selected, by choosing when to start the GC, how much to process on each cycle, and what other features to automatically enable. Possible values are: adaptive - adapt to maintain the given amount of free heap at all times, even during the GC cycle; static - trigger GC when free heap falls below the threshold; aggressive - run GC continuously, try to evacuate everything; compact - run GC more frequently and with deeper targets to free up more memory. |

| ShenandoahUncommit | boolean | Allow to uncommit memory under unused regions and metadata. This optimizes footprint at expense of allocation latency in regions that require committing back. Uncommits would be disabled by some heuristics, or with static heap size. |
