>             Project: Karaf
>          Issue Type: Bug
>            Reporter: Fabian Lange
>            Priority: Major
>
> customer sees this when they run a package upgrade of our karaf distribution
> ```Nov 12 04:15:54 karaf[21250]: Exception in thread "main" java.lang.NullPointerException
> Nov 12 04:15:54 karaf[21250]: at org.apache.karaf.main.Stop.main(Stop.java:60)```
> https://github.com/apache/karaf/blob/master/main/src/main/java/org/apache/karaf/main/Stop.java#L60
> We have the feeling this is kind of a race condition between sending the stop command and deleting the file which contains the stop command.
> whats your thoughts? shouldn'T we at least ensure that `config.shutdownCommand` is non null?
