java.lang.Object | +--org.apache.log4j.helpers.OnlyOnceErrorHandler
The OnlyOnceErrorHandler
implements log4j's default
error handling policy which consists of emitting a message for the
first error in an appender and ignoring all following errors.
The error message is printed on System.err
.
This policy aims at protecting an otherwise working application from being flooded with error messages when logging fails.
