ReplaceJavaUtilDate

[AB-xdev]

Reported by PMD.

Currently there is a lot of java.util.Date and java.util.Calendar in use.

This should be replaced with the newer Java 8+ APIs.

Currently detected on:

I suppressed these warnings for now

Switched to the newer APIs except in BearerTokenRequester class, because the JWT needs a Date Object.
