> Solr server is unable to unmarshall a binary update request where the commitWithin property is set on the UpdateRequest class.
> The client marshalls the request with the following code
> if (updateRequest.getCommitWithin() != -1) {
>       params.add("commitWithin", updateRequest.getCommitWithin());
> }
> The property is an int and when the server unmarshalls, the following error happens (can't cast to List<String> due to an Integer element)
> SEVERE: java.lang.ClassCastException: java.lang.Integer cannot be cast to java.util.List
