Hello I've this piece of code: public static void main(String[] args) { Set<Integer> set1 = new HashSet<Integer>(); Set<Integer> set2 = new HashSet<Integer>(); set1.add(1); set1.add(2); set1.add(3); set1.add(4); set1.add(5); set2.add(4); set2.add(5); set2.add(6); set2.add(7); set2.add(8); SetView<Integer> x = Sets.intersection(set1, set2); set1.removeAll(x); set2.removeAll(x); } and it throws Exception in thread "main" java.util.ConcurrentModificationException at java.util.HashMap$HashIterator.nextEntry(HashMap.java:841) at java.util.HashMap$KeyIterator.next(HashMap.java:877) at com.google.common.collect.Iterators$7.computeNext(Iterators.java:627) at com.google.common.collect.AbstractIterator.tryToComputeNext(AbstractIterator.java:141) at com.google.common.collect.AbstractIterator.hasNext(AbstractIterator.java:136) at java.util.AbstractSet.removeAll(AbstractSet.java:142) at com.Main2.main(Main2.java:30) is this a normal? or a small bug...
