If JMX is enabled for a server it could be possible that the data differ from other API's.

As example the distribution of entries.
a key "one" for a cache encoded as protostream will check the distribution by consistent hash
For REST/CLI is is a byte[111,110,101] internally for JMX it is a String "one"
As result the CH.locate() fuction return a different result.
If the encoding is change to 'java-object' the result will be the same.

So a statement to chapter Register JMX Beans should be added.
JMX was created for embedded and for the server it might have slightly differences so the reliable source of truth is REST/CLI
