Laurent Hasson updated LOG4J2-2135:
-----------------------------------
Description:
With the following code, by the time the program ends, a number of logs are
missing in the output. They may be either lost or not flushed?
{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}
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}
<RollingFile name="FILES" fileName="${log-path}/aaa.log"
filePattern="${log-path}/aaa.%i.log.gz">
<PatternLayout>
<pattern>%d{MMdd.HHmmss.SSS}#%-3t %level{length=1} %15.15c{1}|
%m%ex{20}%n</pattern>
</PatternLayout>
<Policies>

</Policies>
<DefaultRolloverStrategy max="99999" compressionLevel="6"/>
</RollingFile>
