> Several MX bean methods throw _IgniteException / JMException_. Such
> exceptions or their causes cannot be deserialized on the client-side without
> class transfer or class path preparation. The error could look like:
> {code:java}
> java.rmi.UnmarshalException / java.lang.ClassNofFoundException
> {code}
> instead of the desired exception. See the pictures attached. They represent
> results on jconsole.
> The method examples:
> {code:java}
> IgniteMXBean.clusterState(...)
> IgniteMXBean.executeTask(...)
> IgniteClusterMXBean.tag(...)
> {code}
> The simplest solution could be just throwing RuntimeException with the error
> message (example on the picture "Good").
> Or we could deprecate exception-throwing deactivation methods and bring new
> ones returning a string like "Cluster deactivated." / "Cluster activated." or
> "Failed. Cause: ...". But IgniteClusterMXBean already has several deprecated
> cluster-state methods.
> +This ticket suggests another approach:+
> Let's fix existing wrapping with _JMException_ so that it keeps only the
> error message without non-deserializable causes. Let's wrap
> _IgniteException/IgniteCheckedException_ into such _JMException_ in other
> places. This would slightly change the API: several mx-bean methods like
> _IgniteMXBean.clusterState(...)_ will obtain _throws JMException_. User code
> might not be compiled. But why using mx bean API?
