You can find a short description about the function clicking on it:

As the error says, you have to install the JDK 11 on your computer from here and configure JAVA_HOME system environment variable:

Perhaps you have already configured it but with newer version.

You can check this documentation page about releases (and cd and em meaning)

From the official documentation: 

The compact database operation is designed to run concurrently with normal database activity. The operation does consume some system resources, however, and may not complete if the system is under extremely high load. For these reasons, InterSystems recommends running this and other database reorganization operations (including compacting and defragmenting globals) during off-peak hours, and running only one such operation on a system at a time.

Who breaks the wheel pays for it.

You can do it by hand, specifying in the JDBC url used the schema to connect, so you have to disconnect from the previous connection and connect again with the new **CORRECTION** namespace:

jdbc:CACHE://127.0.0.1:1972/NAMESPACE1--> jdbc:CACHE://127.0.0.1:1972/NAMESPACE2

And you can take a look to this article from @Yuri Marx

Regarding the documentation looks like you need to configure the port in the Business Service:

(Configured Web Services exposed using the SOAP Inbound Adapter may also be invoked with this URL parameter but because each configured Inbound Adapter listens on its own TCP/IP port this parameter is just a safety check for them.)

Try with _SYSTEM or SUPERUSER

Have you tried to export it from 2014 and import it into 2018 instance using ^SECURITY command?

I used it with no problem for this application:

The error message talks about a restriction for unauthorized access to %Api.Atelier class, maybe that class override the /login?

I was Java developer for more than 15 years and for me to use arguments by reference was totally disgusting, you can use it in Java, but it's not very common, in Objectscript is the opposite, Output arguments are the rule, no the exception.

Calling instance methods using variables not declared as arguments made me feel dirty.

Is the ID that you are using the same that was generated by the server? 

Long life to @Robert Cemper !
