libjnr-constants-java 0.8.6-8 (amd64 binary) in ubuntu artful

 Java Native Runtime (JNR) is a collection of Java libraries to make
 interfacing with OS-level features easier. JNR uses an alternate
 method to JNI or JNA to achieve programming simplicity while still
 retaining performance.
 .
 The upstream version of this package is now also known as jnr-constants.
 .
 The jnr-constants package gives Java programs access to platform-level
 constants, for example errno values.
