What language and solver does this apply to?
Java

Describe the problem you are trying to solve.
The current Linux jar file cannot be used with the Java module system because it’s file name cannot be converted into an automatic module name. Adding this additional manifest entry will fix this.

Describe the solution you'd like
Add
Automatic-Module-Name: com.google.ortools
to the ortools-java-xxx.jar file

Add
Automatic-Module-Name: com.google.ortools.linux
to the ortools-linux-xxx-xxxx.jar file.

Similar automatic module names should be added to the other os specific jar files (i.e .windows, .mac)
