The intention of the MDS Exeption class is to provide a simple
exeption mechanism for MDS related methods. This includes:
failure to conect to the MDS due to timeout or other problems,
failure during MDS queries,
... .
In case the Exeption is thrown by another underlaying library, it is
the task of the user to properly deal with the exceptions. Such
methods and exceptions can be found in JNDI and Java Networking classes.
