Issue 1090 raised the question of the name of the file generated for java constants.
Decision was taken to change from "Constants.java" to "java_package_nameConstants.java"
It was suggested that the change in the name generation could be made optional, and that's exactly what I need today. Since I'm working on quite old projects, it's a huge pain to change all code to use new filenames.
As it was said, it should represent a very small amount of time to make this an option.
Edit : added a patch proposition
