Executing external processes from Java is a well-known problem area. It is inheriently platform dependent and requires the developer to know and test for platform specific behaviors, for example using cmd.exe on Windows or limited buffer sizes causing deadlocks. The JRE support for this is very limited, albeit better with the new Java SE 1.5 ProcessBuilder class.

The package shall create and maintain a process execution package written in the Java language to be distributed under the ASF license. The Java code might also be complemented with scripts (e.g. Perl scripts) to fully enable execution on some operating systems. The package should aim for supporting a wide range of operating systems while still having a consistent API for all platforms.
