      @Extension(SHRINKING_GC) void shrinkingGC()
      Performs garbage collection making an additional effort to reduce the heap's committed size. After GC, the JVM adjusts the committed heap size based on the amount of used memory, adhering to the -XX:JbrShrinkingGcMaxHeapFreeRatio option. Implemented for G1 only; equivalent to System.gc() for other garbage collectors. Equivalent to System.gc() if -XX:JbrShrinkingGcMaxHeapFreeRatio option is not set. Note: This does not change the minimum (-Xms) or maximum (-Xmx) heap size limits
