Some suggestions:

1. Add upload-database: false to the analyze step. This will prevent the database from being zipped and uploaded.
2. Can you share the workflow file? That will let us know if there is anything that we can improve there.
3. You mentioned that you need to run the C++ build job in the container. Do you also need to do the same for Java? You will likely see better performance if you run outside the container.
4. Are you creating a new container for each job? Is there any possibility that some state is being shared between jobs or workflow runs?
