Problem solved. Weblogic seems to load some log4j stuff in addition to the
application libraries, but you can solve the problems by specifying that your
own classes should have precedence in weblogic-application.xml
<wls:prefer-application-packages>
<wls:package-name>org.apache.logging.log4j</wls:package-name>
</wls:prefer-application-packages>

Subject: RE: RollingFile does not reset file when rolling
I have now tried various combinations of RollingFile and
RollingRandomAccessFile and their settings, but when used from weblogic 12C
with jdk1.8.0_74 I can simply not find a way to make log4j clear the file
after rolling, except if append="false" is added (and everything works fine
when the same configuration is used for logging in eclipse).
Among other things I also tried to remove the Policies tag below so that
SizeBasedTriggerPolicy was not enclosed by a Policies tag. That actually made
things a little worse, and in addition to not clearing the file, when rolling,
there were only made one rolling file with the name .1 instead of the 4 that
was specified.
I think I will end up skipping log4j as I can't skip weblogic :(

Subject: RollingFile does not reset file when rolling
Hi
I use log4j 2.5 on weblogic 12C (By adding the argument
-Dlog4j.Configuration=log4j2.xml) with this configurationfile:
<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="WARN" monitorInterval="320">
<Appenders>
<RollingFile name="com.logica.poltacho.soap.file.appender"
fileName="D:/oracle/config/domains/poltacho3/servers/server1/logs/poltacho-soap.log"
filePattern="D:/oracle/config/domains/poltacho3/servers/server1/logs/poltacho-soap-%i.log">
<PatternLayout>
<Pattern>%d{ISO8601} %-5p %c{1} transId:
%X{transactionId} %m%n</Pattern>
</PatternLayout>
<Policies>
<SizeBasedTriggeringPolicy size="1 MB" />
</Policies>
<DefaultRolloverStrategy max="4" />
</RollingFile>
</Appenders>
<Loggers>
<Logger name="com.logica.poltacho.ws.SoapHandler" level="info"
additivity="false">
<AppenderRef ref="com.logica.poltacho.soap.file.appender" />
</Logger>
</Loggers>
</Configuration>
The file role when increased with about 1 MB but it is not reset! The result is
that both the logfile and new rolled files keep growing in size like this:
poltacho-soap.log 3>MB
poltacho-soap-3.log 3MB
poltacho-soap-2.log 2MB
poltacho-soap-1.log 1MB
If I add append="false" everything works fine and I get the expected result:
poltacho-soap.log 1<MB
poltacho-soap-3.log 1MB
poltacho-soap-2.log 1MB
poltacho-soap-1.log 1MB
It is just that I don't want any existing logfile to be cleared when
application startup.
If I use the same log4j configuration from eclipse in unittests, everything
works fine also without append="false".
Have you seen this before and can you give me a hint for a solution?
