Class ArcSDEDataStore method getFeatureReader(String typeName, Query query) fired NullPointerException by use of Filter.ALL

protected FeatureReader getFeatureReader(String typeName, Query query)
throws IOException {
ArcSDEQuery sdeQuery = null;
FeatureReader reader = null;

try {
FeatureType schema = getSchema(typeName);

// if Filter.ALL.equals(query.getFilter()) the following clall return null;
sdeQuery = ArcSDEQuery.createQuery(this, schema, query);
// so, this will fire a NullPointerExcetion
sdeQuery.execute();

please make the following change as workaround, until a ArcSDEFeatureReader is written.

if (Filter.ALL.equals(query.getFilter()))

{ return new EmptyFeatureReader(schema); }
sdeQuery = ArcSDEQuery.createQuery(this, schema, query);
sdeQuery.execute();

or better

sdeQuery = ArcSDEQuery.createQuery(this, schema, query);
if (sdeQuery == null) { return new EmptyFeatureReader(schema); }

sdeQuery.execute();

tschau
