Description

I've been using the log4j version 1 SocketServer in background without problem. Changing to the TcpSocketServer works in foreground, but when I put it in the background, it shuts down. I've managed to get it working redirecting input from /dev/zero but as this will give continuous nulls, I'm not sure it's an ideal solution:

exec $JAVA_HOME/bin/java -cp $LIB_DIR/log4j-api-2.6.2.jar:$LIB_DIR/log4j-core-2.6.2.jar \
org.apache.logging.log4j.core.net.server.TcpSocketServer \
${LOGPORT} ${BASEDIR}/etc/log4j2.xml </dev/zero >/dev/null 2>&1 &

Is the code intended to be used in background and, if yes what's the recommended way to launch TcpSocketServer? Could a parameter be added to make it a daemon not needing input?
