----------------------------------------

The problem is in ActiveMQ-CPP code in separate JIRA issue: https://issues.apache.org/jira/browse/AMQCPP-551

>             Project: ActiveMQ
>          Issue Type: Bug
>    Affects Versions: 5.10.0
>         Environment: Ubuntu 12.04, Windows Server 2008, Java 1.7
>            Reporter: Pawel Remiszewski
>            Priority: Critical

> Char values in MapMessage cause EOFException when sending message between Java and C++
(both ways).
> When sending messages with char values between Java <=> Java and c++ <=>
c++ it works without errors.
> Don't know if the issue is in Java or c++ part, so I create 2 issues (one for Java ActiveMQ
and one for C++)
> ActiveMQ version used: 5.10.0
> ActiveMQ-CPP version used: 3.8.3
> Also tried with older (3.7.0) and the newest (master from GIT) version of ActiveMQ-CPP
and the same error is thrown.
> Scenario 1 (send message from Java to c++):
> 1. when MapMessage contains only one char value, no exception is thrown on c++ side,
but value is always equals to 0.
> 2. when MapMessage contains char value and some additional values (no matter what type)
EOF exception is thrown on c++ side.
> Scenario 2 (send message from c++ to Java):
> 1. when MapMessage contains at lease one char value, EOF exception is thrown on Java
side.
> Java stacktrace:
