Exceptions annotation

[wsargent]

If an operation throws an exception, then the JMX wrapper assumes that this is a failure to invoke:

javax.management.ReflectionException: Can't convert signature for operation checkHealth

https://github.com/uklimaschewski/JMXWrapper/blob/master/src/com/udojava/jmx/wrapper/JMXBeanWrapper.java#L454

Where it may actually be a listed exception, as defined in the "exceptions" descriptor for the MBeanOperationInfo:

The class names of the exceptions that can be thrown when invoking a constructor or operation, or getting an attribute. The meaning of this field is defined by this specification but the field is not set or used by the JMX API itself. Exceptions thrown when setting an attribute are specified by the field setExceptions.

Exceptions declared here should be passed through without nesting.

i.e. a JMRuntimeException exception with a message

Caused by: javax.management.JMRuntimeException: All host(s) tried for query failed (tried:
/192.168.99.100:9042
com.datastax.driver.core.exceptions.TransportException: [/192.168.99.100:9042] Cannot connect
