Examples of java.util.logging.ErrorManager

java.util.logging.ErrorManager
ErrorManager objects can be attached to Handlers to process any error that occur on a Handler during Logging.
When processing logging output, if a Handler encounters problems then rather than throwing an Exception back to the issuer of the logging call (who is unlikely to be interested) the Handler should call its associated ErrorManager.
