libjnr-netdb-java 1.1.6-1 (amd64 binary) in ubuntu artful

 jnr-netdb is a java interface to getservbyname(3), getservbyport(3).
 .
 It tries to use the native functions if possible, falling back to parsing
 /etc/services directly, and finally to an inbuilt table for use in
 environments where neither native code, nor filesystem access is possible.
