Abbreviations (info, alloc, num, gen, conf, vmems etc) should be avoided:

"numHarvested" ->

"harvested"?
"harvestedMemoryRegions"?

or something else? ...Count?

Labels should use headline-style capitalization:

- "Multi-partition allocation" -> Multi-Partition Allocation"
- "Successful allocation" -> "Successful Allocation"
- "Non-blocking" -> "Non-Blocking"
- "Number of harvested vmems" -> ?

Names must be fixed before JDK 25 is released.
