原文为:

-XX:MetaspaceSize : 指定元空间的初始空间大小

但根据官方文档描述如下:

Sets the size of the allocated class metadata space that will trigger a garbage collection the first time it is exceeded. This threshold for a garbage collection is increased or decreased depending on the amount of metadata used. The default size depends on the platform.

初始大小应该是JVM决定的，这个参数只控制GC的阈值。
