0Auth2.0 issues new token every time even before token's expiration time

Issue

• The access_token expiration default is set to 10 minutes. When invoking the /oauth2/token before the previous token expires, a brand new token is issued instead of the original token. 

Environment

• DXP 7.4

Resolution

• This behavior is expected. Unfortunately, Liferay cannot be configured so that the same token will be reproduced before the 10 minute expiration mark.
