Bruce Brouwer updated LOG4J2-514:
---------------------------------
Attachment: LOG4J2-514.patch.txt
I've added a patch that handles this by subclassing the OutputStreamManager for
the ConsoleAppender so that it always swallows the call to .close().
This also makes it possible to remove the check in OutputStreamManager for
System.err or System.out, which is also included in this patch.
There was also a bunch of unnecessary complexity in dealing with creating
PrintStreams and encodings which I removed as it is all unnecessary when in the
end we only need an OutputStream.
The tests all still pass for me in log4j-core.
> ConsoleAppender closing System.out on Windows

> Key: LOG4J2-514
> URL: https://issues.apache.org/jira/browse/LOG4J2-514
> Project: Log4j 2
> Issue Type: Bug
> Components: Appenders
> Affects Versions: 2.0-beta9
> Environment: Windows 7 64-bit
> Oracle JDK 1.7.0_51
> Reporter: Wolf480 Pl

> If the Console appender is not specified in the configuration file, after the
> configuration is read, the Console appender is being destroyed, which causes
> it to release its OutputStreamManager, When this manager is released and
> closed, it checks if the stream is System.out or System.err, and if it is,
> doesn't close it. But on Windows, ConsoleAppender wraps the System.out into a
> WindowsAnsiOutputStream. The OutputStreamManager closes the stream when it's
> released, and the stream closes the underlaying System.out.

> -I think the easiest solution would be to use new
> FileOutputStream(FileDescriptor.out)) instead of System.out in
> ConsoleAppender implementation.- unfortunately, that would still cause
> System.out to be closed.
> A solution would be to wrap System.out with some FilterStream that overrides
> close() to do nothing.
