It is an Oracle feature source.
There is no error, but no sorting takes place.
The feature source supports sorting because this works well:
query.setSortBy(sortBy);
FeatureCollection featureCollection =
featureSource.getFeatures(query);
Beacuse FeatureCollection can have memory leakage I wanted to avoid using
FeatureCollection.
This does not work:
query.setSortBy(sortBy);
FeatureLayer.setQuery(query);

used in FeatureLayer.setQuery
Do you have any more details? What happens beyond - does not work. What feature
source are you working with?
Behind the scenes we try and combine your query with each query defined by your
style - and then draw the features as they come back.
Depending on the implementation if feature source ( and if it supports sorting
) you may get different behavior.
