Review Comment:
this is no way to create CharArrayWriter in original constructor.
because original constructor first need call supper constructor. supper
constructor need a CharArrayWriter as parameter.
```
private LogDivertAppender(OperationManager operationManager,
OperationLog.LoggingLevel loggingMode, CharArrayWriter writer) {
super("LogDivertAppender", initLayout(loggingMode), null, false, true,
Property.EMPTY_ARRAY,
new WriterManager(writer, "LogDivertAppender",
initLayout(loggingMode), true));
}
```
if create CharArrayWriter in original constructor like you suggest compile
will failed.
