[wilkinsona]

I’ve opened #28932 and #28931 for problems that are related to this. Once those have been fixed, we’ll review this problem again and see what, if anything, more we need to do.

@wilkinsona Yes, it does look like a different problem as the exception and message are different. But I think the core problem could be a failure to detect and set the configs specified by the application properties file, because I tried to set several properties (reading and following the doc) for preventing Hibernate from initializing database and it didn’t make any difference.

The doc says that Hibernate takes different default values depending on schema manager detection and on whether database is embedded, and it looks at Connection type and JDBC URL. As the URL is the main difference between QA and Local config properties here, I think it could be impacting or overriding some configs.

There are many other projects here with similar properties in their QA and Prod environments, but with version 2.3.x, and they don’t present this problem! The supposed failure could be the cause for both database’s type detection and schema script detection failures.

Nevertheless I’ll double check the environment variables.
