@sijie
in order to load the native library during JUnit tests I have added these
lines to bookkeeper-server/pom.xml
```
<plugin>
<artifactId>maven-surefire-plugin</artifactId>
<configuration>
<argLine>-Xmx2G -Djava.net.preferIPv4Stack=true
-Djava.library.path=${project.build.directory}/native/target/usr/local/lib</argLine>
</configuration>
</plugin>
```
Now:
- no error in logs
- tests run like in "production mode"
new logs:
> 2017-04-21 08:53:51,595 - INFO - [BookieJournal-15001:NativeIO@41] -
Loading bookkeeper native library.
> 2017-04-21 08:53:51,596 - INFO - [BookieJournal-15001:NativeIO@44] -
Loaded bookkeeper native library. Enabled Native IO.
Do you think we can add that configuration to the pom.xml ?
