Examples of org.rssowl.core.util.LoggingSafeRunnable

org.rssowl.core.util.LoggingSafeRunnable
Abstract implementation of ISafeRunnable that is logging any {@link CoreException} using the Plugin's Log Mechanism.
TODO Create ExceptionListener that allows to listen for these Runtime Exceptions. That would allow the UI to show an Error Dialog with Details of the Error.

TODO Note that the SafeRunner is already logging any exception to the log before it calls the handleException() method!
