Erm... what file is it trying to copy? Is it looking for a repository.xml? (If
so: classpath, I assume?)
The problem is that the sling.home property is not set and hence the
File.getParentFile() may throw a NullPointerException.
The fix is for the Activator.initConfig() method of jackrabbit-server to check
for this situation and try to use the bundle private data area or the current
working directory instead.
