hashmap bug

[jamborta]

hi guys,

I'm sure it's something silly but I can't figure out what's wrong with this code:

        HashMap allWeights = weights.getAllWeights();
        Iterator itr = allWeights.entrySet().iterator();
        log.info("Number of users in the dataset: {}", allWeights.size());
        Collection<Callable<Void>> evaluatorCallables = new ArrayList<Callable<Void>>();
        while (itr.hasNext()) {
            Map.Entry entry = (Map.Entry) itr.next();
            long uid = (Long) entry.getKey();
            ArrayList<LongDoublePair> movieList = (ArrayList<LongDoublePair>) entry.getValue();
            evaluatorCallables.add(new EvaluatorCallable(uid, movieList, testModel));
        }
        log.info("Evaluator callables size {}", evaluatorCallables.size());

it prints the following:

INFO: Number of users in the dataset: 6033
INFO: Evaluator callables size 3182

but these numbers should be identical.
thanks for your help
Tom

Maybe another thread is altering the map?

Perhaps it might be clearer if you removed the extraneous dependencies and posted a SSCCE.
