> I got this NPE attempting to roll from 9.0.4 to develop (starting a develop server using a 9.0.4 locator):
> {code}
> Exception in thread "main" java.lang.NullPointerException
> 	at java.util.Arrays.stream(Arrays.java:5004)
> 	at java.util.stream.Stream.of(Stream.java:1000)

> In this case, jarFileNames is null, so this line fails:
> {code}logger.info("Got response with jars: {}", Stream.of(jarFileNames).collect(joining(",")));{code}
> Moving the logger message inside the null checks fixes the issue:
> {code}if (jarFileNames != null && jarBytes != null) {
>   logger.info("Got response with jars: {}", Stream.of(jarFileNames).collect(joining(",")));{code}
