Description

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.
