> I got this NPE attempting to roll from 9.0.4 to develop (starting a develop server using
a 9.0.4 locator):

> 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}
