> StandardFlowComparator.compareProperties() throws a NullPointerException when
> getPropertyDescriptors() returns null for a component being compared.
>
> {code:java}
> Exception in thread "main" java.lang.NullPointerException: Cannot invoke
> "java.util.Map.get(Object)" because "descriptorsB" is null at
> o.a.n.registry.flow.diff.StandardFlowComparator.lambda$compareProperties$2(StandardFlowComparator.java:391)
> at java.base/java.util.LinkedHashMap.forEach(Unknown Source) at
> o.a.n.registry.flow.diff.StandardFlowComparator.compareProperties(StandardFlowComparator.java:389){code}
>
> The fix wraps all compareProperties call sites with the existing
> nullToEmpty() method to be consistent with VersionedFlowRegistryClient.
