This file is only used by Oracle. It's used to interact with our 
dependency management and build configuration system ("jib"), which is 
internal. We keep it in the source code since this configuration is very 
highly version specific and frequently changes in lock step with other 
source code changes. While the exact meaning of the contents of the file 
isn't obvious to an external reader, certain things pertaining to how 
Oracle configures builds can still be gleaned from it and may be useful 
to some (current compiler versions, values of some configure options etc).

I would very much recommend against trying to merge changes here for 
OpenJDK update releases.
