Hi Steinar, Yes this is possible for some exceptional cases by cloning the source package with a new name (typically 'foo' become 'foo4' or 'foo-4.0'), renaming the /usr/share/java files and changing the generic 'debian' version in the Maven repository with something like 4.x. We have some duplicated packages in the archive like junit/junit4, plexus-utils/plexus-utils2, antlr3/antlr3.2, asm/asm3/asm4... You can get a look at them if you need an example, but keep in mind this is really a last recourse solution if porting the code to the version of the library in Debian is too difficult or risky. Do you have a compatibility issue with libjna-java? Emmanuel Bourg
