Most information that is printed about Metaspace from the garbage collector (GC) has been moved into Metaspace-related sources.

For historical reasons, some Metaspace information has been printed from the GC. Since Metaspace and the GC are two separate things, it is reasonable to separate accessing information about the two. There are already methods to get information about Metaspace without getting information about the GC, where the information has been moved to.

To get information about Metaspace that was once part of the `GC.heap_info` jcmd, refer to the existing `VM.metaspace` jcmd instead.
