What are you up to? Do you really want to address you EJBs with "java-
gobal/someejb-2.3.12-SNAPSHOT"? Or is it more like "java-gobal/someejb-2.3" 
, i.e. a "major.minor" pattern?

If it is the latter, you might simply use "sed" and a regular expression to 
update the files from command line every time you update a major/minor 
version and ensure with the verifier plugin, that no java file contains an 
@EJB line that does not contain current major.minor.
