Nee, die map is van objecten op doubles, en ik zoek op integer (als object)

I already found it, but I thought this was pretty odd at first, so who can tell me what might be going wrong here :
code :
Map<Object,Double> die = classifier.distributionForInstance(instance); double estimate = 0.0; if (die != null) { System.out.println("size " + die.size()); estimate = die.get(new Integer(1)); <-- line 94 } -------------------------------------------------------------------------
output :
size 2 java.lang.NullPointerException at be.svlandeg.pi.classification.JavaMLClassifier.eval(JavaMLClassifier.java:94)
Obviously, "die" is not null...
