Description
Doing the following will throw an Index out of bounds exception.
final VarCharVector vector = new VarCharVector(field, allocator); vector.allocateNew(); vector.getMutator().setValueCount(100);
The expected behavior is to resize the array appropriately. If an index is uninitialized you should not call get for that index.
