run consumer as background service

I have been trying to use it as background service on ubuntu 16.06. absolute paths gives exception
` /home/ubuntu/kcl/bin/kcl-bootstrap --java /usr/bin/java -e -p /home/ubuntu/kcl/samples/basic_sample/consumer/sample.properties -s
`
results in
```
Starting Multi-Lang Daemon ...
Exception in thread "main" java.lang.NullPointerException
at java.util.Properties$LineReader.readLine(Properties.java:434)

at com.amazonaws.services.kinesis.multilang.MultiLangDaemonConfig.(MultiLangDaemonConfig.java:57)
```

also tried with `/etc/init.d/` and changed directory to `consumer` folder and ran `../../../bin/kcl-bootstrap --java /usr/bin/java -e -p ./sample.properties -s`

is there any way I can run it as background service (relaunch if it crashes and start on boot)
thanks for any help

Start with bin/kcl-bootstrap and the sample.properties path used in the report, then inspect MultiLangDaemonConfig.loadProperties at the stack-trace location. Reproduce the absolute-path and consumer-directory commands on Ubuntu; done means the consumer starts without the NullPointerException and the supported background-service behavior, including restart and boot startup, is established.
