I authorized Bitbucket Server to access Jenkins on my behalf. Now when I view the "Authorized tokens" in Jenkins, it displays "2021-43-14 04:43" as the creation date. That is clearly wrong as this year does not have 43 months in it.

OAuthTokenConfiguration/index.properties looks related:

bitbucket.oauth.token.creation.date.value={0,date,yyyy-mm-dd hh:mm}

Perhaps the first "mm" should be something else, but I'm not familiar with this syntax.
