Cause

Configuraiton.

Environment

Release : 12.3

Component : ANALYTICS ON PREMISE

Resolution

The datasource.ae.password= was defined as (file application.properties): 

datasource.ae.password=--Encrypted_password;Mars_Connection=Yes

Once ;Mars_Connection=Yes was removed the application started as expected.
