Description

A developer new to the subject of "daemonizing" may be left with an unclear picture of what he'd gain from using Commons Daemon with his app after reading the intro:

http://commons.apache.org/proper/commons-daemon/index.html

The features and benefits of the software could be stated in more clear terms.

Here're potential some suggestions for a list of features:

• automatically restart JVM if it dies
• enable secure shutdown of JVM process using standard OS mechanisms (Tomcat TCP based shutdown mechanism is error-prone and unsecure)
• redirect of STDERR/STDOUT and set JVM process name
• allow integration with OS init script mechanisms (record JVM process pid)
• detach JVM process from parent process and console
• run JVM and application with reduced OS privileges
• allow coordinating log file management with OS tools such as logrotate (reopen log files with signal SIGUSR1)
