‑Xenableexplicitgc / ‑Xdisableexplicitgc

Enables and disables garbage collection (GC) when calls are made to System.gc().

Syntax

Setting	Effect	Default
-Xenableexplicitgc	Enable GC	yes
-Xdisableexplicitgc	Disable GC

Explanation

Although it is possible to programmatically trigger a garbage collection by calling System.gc(), performance can be adversely affected by halting the application before it is really necessary. Use this option to prevent the VM responding to application requests for a garage collection cycle.
