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.
