Description

struct QueryResult {
1: required list<list<string>> rows;
}
service QueryService{
QueryResult query();
}

Using TJSONProtocol the list<list<string>> is transmitted correctly but deserialized wrong. Only the first sublist will contain the correct string values the second, third and so on will be empty. The error is a combination of readListBegin, readListEnd and readString (in thrift.js) which somehow interacts wrongly with the internal rstack when lists are included in lists.

As a temporary solution until the deserialization is fixed I advice others to create an intermediate struct which contains the sublists.
