Answer 1

Good article http://www.javaworld.com/javaworld/jw-12-2000/jw-1229-traps.html Its for the old way but gives good insight.

Article I haven't read of converting to the new way:

From Runtime.exec() to ProcessBuilder

Answer 2

The "&" works in this case like "|" etc.:

Runtime.getRuntime().exec("./test.sh &");

(I made a test on Debian with and endless loop in a shell script and the java got back the control after starting the script)
