Good day!
I encountered a problem with JavaAPI when I tried to run this simple program:

   CycAccess cycAccess=new CycAccess();
   CycList gaf = cycAccess.makeCycList("(#$implies (#$isa ?X #$Dog) (#$not (#$isa ?X #$Cat)))");
   CycFort mt = cycAccess.getKnownConstantByName("#$UniversalVocabularyMt");
   HashMap queryProperties = new HashMap();
   boolean isQueryTrue = cycAccess.isQueryTrue(gaf, mt, queryProperties);
   System.out.println(isQueryTrue);

It printed "false".
But when I ask the same question using Web Interface, the return was "true".

What is the problem?
