public class ConsoleAppender
extends org.apache.log4j.WriterAppender
System.out
or
System.err
using a layout specified by the user. The
default target is System.out
.
Modification was done in JBoss fork to use the real stdout/stderr
via FileDescriptor.out
/FileDescriptor.err
instead of
System.out
/System.err
, because in some cases, the standard
stream may be reassigned.
