Examples of org.rhq.core.clientapi.agent.PluginContainerException

org.rhq.core.clientapi.agent.PluginContainerException
This generic exception thrown by the plugin container is part of its client API; thus this exception is available to both the plugin container as well as its remote clients.
Make sure that when constructing these exceptions, that any {@link #getCause() cause} is also available to remoteclients as well! If you are unsure, wrap the cause in a {@link org.rhq.core.util.exception.WrappedRemotingException}before passing it to this class' constructor.
