org.esa.snap.product.library.v2.activator.ProductLibraryActivator: Failed to initialize the database.

When running Some S1tbx processes in the image, I get this error/warning (the processing still succeeds):

INFO: org.esa.snap.core.gpf.operators.tooladapter.ToolAdapterIO: Initializing external tool adapters

So some part of SNAP generates this path ?/.snap/product-library/products;AUTO_SERVER=TRUE and does not like it, duh. Could be that the ? should be a ~, such that the link points to the regular user home path ~/.snap.

This happened first when I was building the docker image as root. I tried adding a user with a normal own HOME dir, too, to no avail. Might need to make sure that the environment variable is set correctly at runtime.
