Safe runnables represent blocks of code and associated exception
handlers.  They are typically used when a plug-in needs to call some
untrusted code (e.g., code contributed by another plug-in via an
extension).

This interface can be used without OSGi running.

Clients may implement this interface.

Handles an exception thrown by this runnable's run method. The processing done here should be specific to the particular use case for this runnable. Generalized exception processing, including logging in the Platform's log, is done by the SafeRunner. 
 All exceptions from the run method are passed to this method, along with certain Error types that are typically caused by programming errors in the untrusted code being run. 
Params:
exception – an exception which occurred during processing the body of this runnable (i.e., in run)
