Customizable Access Token sample script contains error

Bug description

The out of the box sample OAuth2 Access Token Modification Script contains an error. Line 75 refers to

"Remove a native field from the token entry, that was set by AM. For complete list of remove* methods see the JavaDoc for org.forgerock.oauth2.core.AccessToken class" It then lists the following method:

accessToken.removeTokenName()

This method should be accessToken.removeField()

How to reproduce the issue

Edit OAuth2 Access Token Modification Script in attempt to remove a claim we ship by default.

Expected behaviour

Remove a specified claim

Current behaviour

Removes name of token

Work around

Use accessToken.removeField() method instead of accessToken.removeName() method.
