             Summary: NPE when jarFileNames is null in ClusterConfigurationLoader

          Issue Type: Bug
          Components: gfsh
            Reporter: Emily Yeh

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

Exception in thread "main" java.lang.NullPointerException
	at java.util.Arrays.stream(Arrays.java:5004)
	at java.util.stream.Stream.of(Stream.java:1000)
	at org.apache.geode.internal.cache.ClusterConfigurationLoader.deployJarsReceivedFromClusterConfiguration(ClusterConfigurationLoader.java:75)
	at org.apache.geode.internal.cache.GemFireCacheImpl.deployJarsReceivedFromClusterConfiguration(GemFireCacheImpl.java:1033)
	at org.apache.geode.internal.cache.GemFireCacheImpl.initialize(GemFireCacheImpl.java:1150)
	at org.apache.geode.internal.cache.GemFireCacheImpl.basicCreate(GemFireCacheImpl.java:758)
	at org.apache.geode.internal.cache.GemFireCacheImpl.create(GemFireCacheImpl.java:745)
	at org.apache.geode.cache.CacheFactory.create(CacheFactory.java:
    
In this case, jarFileNames is null, so this line fails:

logger.info("Got response with jars: {}", Stream.of(jarFileNames).collect(joining(",")));

Moving the logger message inside the null checks fixes the issue:

if (jarFileNames != null && jarBytes != null) {
  logger.info("Got response with jars: {}", Stream.of(jarFileNames).collect(joining(",")));
