I think this is an explanation of the problem. Log4J ConsoleAppender
descends from WriterAppender (or something similar) and it remembers
System.out (or System.err) values during initialization. If later
anybody changes System.out (or .err), Log4J does not notice it. I would
suggest writing your own Appender that always uses System.out (or
System.err) instead of storing its value inside.

Seriously, I'd at least appreciate any insight/speculation as to where the
problem might be. If nobody knows exactly what is going on I'll have to look
at the source and it would be nice to have some opinions about where to start
(e.g. ANT vs JUnit, specific modules/classes, etc.).

Subject: JUnit, ANT, log4j, System.out issue
Hello,
I am experiencing an issue with the combination of ANT, JUnit and
log4j. Here's the situation. The ANT build file uses the <junit>
task. Log4j is configured to print to the console. There are also
times when the unit tests use System.out directly. The problem is
that the log4j statements are not captured by the <junit> as part of
the standard output. The logging statements do appear on the console
when I run the tests. But since they are not captured by <junit>,
they do not appear in the XML files and are lost forever.
I originally posted this message to the JUnit list. Since then I have
discovered that if I do not fork the JUnit process everything behaves
as I expect. Not forking the JUnit process is not really an option,
as there are quite a few unit tests and I run into memory issues.
Here's the ANT target:
<target name="run-test" depends="init,test-setup">
<!-- execute the test -->
<junit fork="yes"
dir="${basedir}"
haltonfailure="${test.halt.on.failure}"
printsummary="withOutAndErr">
<classpath refid="test.classpath" />
<formatter type="xml" />
<formatter type="plain" usefile="false"/>
<jvmarg line="${test.jvmargs}" />
<batchtest fork="yes" todir="${test.report.xml.dir}">
<fileset dir="${test.src}" >
<include name="${test.full.includes}" />
<exclude name="${test.full.excludes}" />
</fileset>
</batchtest>
</junit>
</target>
Here's the log4j configuration:
<log4j:configuration debug="false">
<appender name="SYS_OUT" class="org.apache.log4j.ConsoleAppender">
<param name="Target" value="System.out"/>
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%-5p %c{2} -%m%n"/>
</layout>
</appender>
<root>
<level value="INFO"/>
<appender-ref ref="SYS_OUT"/>
</root>
</log4j:configuration>
Version information:
[09:19 C:/] ant -version
Apache Ant version 1.6.0 compiled on December 18 2003
log4j 1.2.8
JUnit 3.8.1
If anybody could enlighten me on the subject, I'd appreciate it.
Thanks,
