I'm in the process of stripping out some OSGi support, and I missed one import.
The exception identifies "init.clj", but I'd prefer to see the full path there, as I have a few different "init.clj" files in my overall project.
While it's reasonable to want this for your case, having long path names in a stacktrace could be inconvenient for others. I'd recommend posting your desired change on the dev list - https://groups.google.com/forum/?fromgroups#!forum/clojure-dev . If they're ok with it, then I'd recommend submitting a patch.
Enhanced error reporting is always an enhancement request, not a defect.
