Laurent Hasson updated LOG4J2-2135:
-----------------------------------
Description:
With the following code
{code:java}
public class Log4JTest
{
protected static final Logger Log =
LogManager.getLogger(Log4JTest.class.getName());
protected static final int MAX = 10;
public static void main(String[] args)
{
for (int i = 0; i < MAX; ++i)
{
for (int j = 0; j < MAX; ++j)
{
Log.fatal("Fatal i=" + i + "; j=" + j + ";");
Log.error("Error i=" + i + "; j=" + j + ";");
Log.warn("Warn i=" + i + "; j=" + j + ";");
Log.info("Info i=" + i + "; j=" + j + ";");
Log.debug("Debug i=" + i + "; j=" + j + ";");
Log.trace("Trace i=" + i + "; j=" + j + ";");
}
}
Log.info("DONE.");
}
{code}
and log4j2.xml configuration
{code:xml}
<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="info">
<Appenders>
<Console name="Console" target="SYSTEM_OUT" >
<PatternLayout>
<pattern>%d{MMdd.HHmmss.SSS}#%-3t %level{length=1}
%15.15c{1}| %m%ex{20}%n</pattern>
</PatternLayout>
</Console>
</Appenders>
<Loggers>
<AsyncRoot level="debug">
<AppenderRef ref="Console" />
</AsyncRoot>
</Loggers>
</Configuration>
{code}
by the time the program ends, a number of logs are missing in the output. They
may be either lost or not flushed? I'd expect the program to end and all log
messages to be output properly, ending with the "DONE" message. If i change the
config file to a rolling appender, i can observe the same behavior, i.e.,
missing messages.
{code:xml}
