Illegal reflective access by org.github.jamm.MemoryMeter to field java.util.concurrent.atomic.AtomicReference.value

I am using clj-memory-meter and get this:

WARNING: An illegal reflective access operation has occurred
WARNING: Illegal reflective access by org.github.jamm.MemoryMeter (file:/tmp/jamm1846689842101955943.jar) to field java.util.concurrent.atomic.AtomicReference.value
WARNING: Please consider reporting this to the maintainers of org.github.jamm.MemoryMeter
WARNING: Use --illegal-access=warn to enable warnings of further illegal reflective access operations
WARNING: All illegal access operations will be denied in a future release

It sounds rather bad, so I figured it would be best to report it even though I can only guess what it means.
