The Simplicité Instance Manager (SIM) version 5.18 has been released.
This version prevents instance name to use underscore character
_ due to new hostname enforcement rules applied by Tomcat versions above 8.5.31 and 9.0.8.
If you have any existing instance name with underscore character, make sure to rename it with a strict alphanumerical name (the hyphen/minus character
- is already forbidden due to PostgreSQL naming policies). If you don’t do so Tomcat will return a
HTTP 400 error.
See this document for details on the SIM usage
