This LogDivertAppender inherits from WriterAppender, and when its method subAppend(event) is invoked, the first line super.subAppend(event) will write the log into writer. Not matter the OperationLog is null or not, the writer should be reset, since the log in it will be not used any more in this Appender. Otherwise, the remaining log in writer might mix with next log. So maybe we could keep the access and null check order. :) - Dong ----------------------------------------------------------- This is an automatically generated e-mail.
