** Description changed:
After upgrading to 4.4.0-81-generic some a third party service failed to
start after investigating I managed to reproduce the issue using the
following method. Note: Issue does not occur after down grading the
kernel to 4.4.0-79-generic, but as this report suggests, it is still
there in 4.4.0-82-generic
Created a Java file Run.java
import java.util.Date;
import org.apache.commons.daemon.Daemon;
import org.apache.commons.daemon.DaemonContext;
import org.apache.commons.daemon.DaemonInitException;
public class Run implements Daemon {
private class Runner extends Thread {
public void run() {
synchronized(this) {
try {
System.out.println(new Date() + " running ...");
wait();
} catch (Exception e) {}
}
}
}
Runner r = new Runner();
@Override
public void init(DaemonContext context) throws DaemonInitException,
Exception {}
@Override
public void start() throws Exception {
System.out.println(new Date() + " Staring...");
r.start();
}
@Override
public void stop() throws Exception {
synchronized(r) {
System.out.println(new Date() + " Stopping ...");
r.notify();
}
}
@Override
public void destroy() {}
}
Compiled with
javac -cp /usr/share/java/commons-daemon-1.0.15.jar Run.java
Created a script to launch through JSVC
# Setup variables

do_exec
else
echo "service not running, will do nothing"
exit 1
fi

echo "usage: daemon {start|stop|restart}" >&2
exit 3

Ran the script with
./service start
The error log file in /tmp/example.err contains.
