Eval in java returns me a NULL type for the queries that returns me 'others' in xquery

[sravanr]

I am expecting my xquery to match OTHER type in java but it is matching to NULL type.

For simplicity I am pasting the REST query

curl -i --digest --user admin:admin -d 'xquery=xdmp:functions()[2]' -X POST 'http://localhost:8000/eval'

and java code

 String query1 = "xdmp:functions()[2]";
ServerEvaluationCall evl = client.newServerEval();
     EvalResultIterator evr = evl.xquery(query1 ).eval();
     while(evr.hasNext())
     {
         EvalResult er =evr.next();
         if(er.getType().equals(Type.XML){

         }else if(er.getType().equals(Type.NULL)){
         System.out.println("Testing is empty sequence is NUll?"+er.getAs(String.class));
         }else if(er.getType().equals(Type.OTHER)){
                 System.out.println("Testing is Others? "+er.getAs(String.class));       
             }
                 else{
}
}
