Package: jsvc
Version: 1.0.15-6+deb8u1
Severity: important
When trying to start a very simple java daemon on jessie jsvc through systemd
we obtain this error message:
Service killed by signal 11
Then we need to SIGKILL the parent process.
The problem appeared on our servers after the last apt upgrade which installed
the following packages (the servers were rebooted after the upgrade):
Upgrade: python-acme:amd64 (0.10.2-1~bpo8+1, 0.10.2-1~bpo8+2),

I've installed a fresh VM to try to reproduce this bug on a new machine :
- installed jessie with ssh and standard utilities
- installed openjdk-8-jre from backports
- installed jsvc
- Created this java file:
-------------------------
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 {
wait();
} catch (Exception e) {}
}
}
}
Runner r = new Runner();
@Override
public void init(DaemonContext context) throws DaemonInitException,
Exception {}
@Override
public void start() throws Exception {
r.start();
}
@Override
public void stop() throws Exception {
synchronized(r) {
r.notify();
}
}
@Override
public void destroy() {}
}
------------------------
Which basically starts and wait for termination
- compiled with:
$ javac -cp /usr/share/java/commons-daemon-1.0.15.jar Run.java
- and tried to run with:
$ /usr/bin/jsvc -nodetach -outfile '&2' -errfile '&2' -pidfile /tmp/jsvc.pid
-cp /usr/share/java/commons-daemon-1.0.15.jar -java-home
/usr/lib/jvm/java-8-openjdk-amd64 Run
Service killed by signal 11
I would upgrade to stretch but it's not yet supported on our OVH vps.
Thanks for your help !
