A Process Management Library for Java

Primal

A Process Management Library for the Java Platform

This library is still under development

The Java Process API has been around for a while now, and even though it had received some significant updates in the past major releases of the platform, there are still plenty of possibilities to shoot yourself in the foot. For more details read the section about Issues with the Process API.

The goal of this library is to provide a usable API to be used as an alternative to Process and ProcessBuilder which

1. works around the issues with Process API
2. provide a set of useful Features
