Description

jsvc is used to start the cdm-server as daemon. Jetty 8 is however no longer using jsvc it is using the apache commons-daemon which actually is the successor to jsvc. The commons-daemon website still suggests the usage of the native jsvc library but jetty no longer has a package dependency to it.

jetty 8 startup command:

/usr/lib/jvm/java-7-openjdk-amd64/jre/bin/java -Xmx256m -Djava.awt.headless=true -Djava.io.tmpdir=/var/cache/jetty8/data -Djava.library.path=/usr/lib -DSTART=/etc/jetty8/start.config -Djetty.home=/usr/share/jetty8 -Djetty.logs=/var/log/jetty8 -Djetty.state=/var/lib/jetty8/jetty.state -Djetty.host=0.0.0.0 -Djetty.port=8080 -cp /usr/share/java/commons-daemon.jar:/usr/share/jetty8/start.jar:/usr/lib/jvm/java-7-openjdk-amd64/jre/lib/tools.jar org.eclipse.jetty.start.Main --daemon etc/jetty-logging.xml etc/jetty-started.xml

jsvc seems to cause Sigfaults in the jvm with the latest debian jessy updates, which where:

after starting the cdm-server daemon jsvc starts up normally and subsequenlty starts the jvm process which crashes early when loading the java runtime class libraries:

I tested a package upgrade on a clone from edit-jobber-1 by which kernel version 3.16.43-2+deb8u3 was installed. According to the above referenced post this is exactly the version which fixed the problem with jsvc.
After installing the upgrade the cdm-server reboots normally again. Even after a full system restart everything is ok.
