> URL: https://issues.apache.org/activemq/browse/AMQCPP-149
> Project: ActiveMQ C++ Client
> Issue Type: Bug
> Components: Openwire
> Affects Versions: 2.0, 2.0.1, 2.1
> Reporter: Marco Renz
> Assignee: Timothy Bish
> Fix For: 2.1.1

> Send message from a java client with a string property whereas the value is the empty string.
> Try to receive this message with a C++ client.
> Result: C++ client crashs.
> Reason:
> In OpenwireStringSupport::readString a std::vector is initialized to the string length which is 0. Then DataInputStream::readFully is called with the vector as argument. But this method tries to get the element at index 0 of the vector without any check. But there is no element in the vector at all...
> Proposed solution:
> DataInputStream::readFully should check the size of the vector before accessing elements.
> Further info:
> If the message is send from C++ client then there is no problem. Maybe /0 is used so that the vector has at least a size of 1.
> I got that probelm with 2.0.1. I did not tried 2.1 but checked the code.
