SMTP Sasl authentication failed : password is too long

[pniotout]

Describe the bug
I'm connecting to a smtp server via SASL / XOAUTH2 with a long password (1508 characters)

got the error :
DEBUG SMTP: protocolConnect login, host=.fr, user=@*******.fr, password=
DEBUG SMTP: Authenticate with SASL
DEBUG SMTP: SASL mechanisms allowed: XOAUTH2
DEBUG SMTP: SASL Mechanisms:
DEBUG SMTP: XOAUTH2
DEBUG SMTP:

DEBUG SMTP: SASL callback 1: javax.security.auth.callback.PasswordCallback@43c67247
AUTH XOAUTH2 [LONG PASSWORD]
500 5.5.2 Line too long
DEBUG SMTP: SASL authentication failed

Expected behavior
I must have been connected

Additional context
I found the problem is in SMTPSaslAuthenticator class :

proposed solution :

Tested with the same password and it's working great.
