/** A purely convenience class. MBeanServerConnection interface methods throw a lot of
* exceptions and an implementation of this interface generally ends up writing
* large try-catch blocks.
* <P>
* This class has methods whose names are chosen from the
* class MBeanServerRequestMessage {@link javax.management.remote.message.MBeanServerRequestMessage}
* and all they do is return specific exceptions cast from the passed exception.
* If the passed exception is none of the exceptions that a method throws, (which
* should not be the case most of the times) then a ClassCastException results.
* <P>
* The principal advantage of this class is that it does the repetitive work at
* one place and moves the exception conversion task away from actual MBeanServerConnection
* implementation. This way some reuse of the methods throwing the same exceptions
* is achieved.
