private static ImmutableMetadata getFlagMetadata(Map<String, Object> currentFlagSetMetadata, FeatureFlag flag) {

currentFlagSetMetadata and/or flag.getMetadata() can be null, causing entrySet() to throw NPE.

A defensive check for null should be added to fix the problem for servers that don't suport metadata.

Hi, I'd like to work on this issue. I'll add null checks for currentFlagSetMetadata and flag.getMetadata() before calling entrySet(). I'll treat null as an empty map to handle servers that don't support metadata.
