Re: System.err gone? -- found it
I found it. And it indeed closes System.err. Here's the stack trace.
(manually typed in from looking at JBuilder's debugger window --
there may be typos, after all, it's me typing ...)
java.io.Printstream.close # 117 -- and this instance is System.err
java.io.OutputStreamWriter.close # 259
java.io.FilterWriter.close # 89
WriterAppender.closeWriter # 212
WriterAppender.reset # 331
WriterAppender.close # 202
AppenderAttachableImpl.removeAllAppenders # 109
Category.remoteAllAppenders # 897
PropertyConfigurator.parseCategory # 586
PropertyConfigurator.configureRootCategory # 502
PropertyConfigurator.doConfigure # 410
PropertyConfigurator.configure # 341
The config file being set in the above call is:
log4j.rootCategory=DEBUG, A1, A2
log4j.categoryFactory=com.r_objects.util.logging.Log$LogFactory
# A1 is set to be a ConsoleAppender
log4j.appender.A1=org.apache.log4j.ConsoleAppender
log4j.appender.A1.layout=org.apache.log4j.PatternLayout
log4j.appender.A1.layout.ConversionPattern=%d %-5p [%t] (%13F:%L)%n - %m%n%n
# Set options for appender named "A2"
log4j.appender.A2=org.apache.log4j.FileAppender
log4j.appender.A2.File=settings.log
log4j.appender.A2.layout=org.apache.log4j.PatternLayout
log4j.appender.A2.layout.ConversionPattern=%-5p %d [%t] %-17c{3}
(%13F:%L) %n @ %C.%M:%L%n%n - %m%n-----------------%n
My (admittedly uneducated) guess would be that ConsoleAppender not
only needs to override closeWriter() -- which it does -- but also
close().
Let me know if you have any questions.

I believe it is 1.1.3.
Thanks for your quick response.

Johannes,
According to your stack trace ConsoleAppender.closeWriter is not overriding WriterAppender.closeWriter which explains why System.eer is being closed. I'll look into this ASAP. Which version of log4j is this by the way? Thanks, Ceki
