7.5.0 launch error

Error 500 - Internal Server Error at Bonita's first launch

I have installed the Bonita 7.5.2 Tomcat 7.0.76 Bundle and PostgreSQL 9.5, when I run the start-bonita.sh script all is fine and I can access the Tomcat home page through localhost:8080 but when I try to access the Bonita login page at localhost:8080/bonita I get an error 500 entitled "Internal Server Error" by Bonita.
Here it is what I have in the bonita.2018-06-01.log file :

Bonita BPM 7.5.0 will not launch Mac OS 10.12.5 (16F73), Java (build 1.8.0_131-b11)

Here is the log:
