SMTP Sasl authentication failed : password is too long

**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: 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 :

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