In the OpenJDK build that means this file, along with the accompanying `.ipdb` file, will end up in the JDK image. To fix this, we need to apply a similar fix to JDK-8372643 and add an extra parameter that defines the location of this file.

Seems so. Could you please confirm this with the full test set in mach5? It is not necessary to revert "that revert" until https://github.com/openjdk/jdk/pull/28676  is fixed, but it would be good to know that the issue on windows is resolved.
