Purging the access token has two different ways to set it based on the version.
I am not able to understand clearly the difference between =<4.15 and =>4.16 versions.
For 4.16 and later, can the property
keymanagement.oauth20.access.token.purge.after.seconds
be set using the Management API (i.e. same way done in versions =< 4.15) or does have to be done via the mp-properties file explicitly and the 4.15 way is no longer support in 4.16 and later?
