Description

This may not be possible, but it would be very useful. Currently the only definitive way to determine whether JNA is enabled and that it's able to lock the memory it needs is to look at the startup log.

It would be great if there was a way to store whether it is enabled so that jmx (or nodetool) could easily tell if JNA was enabled and whether it was able to lock the memory.
