On any system you need to pump (read and discard read data) STDOUT and 
STDERR in separate threads from the child process. Otherwise the process 
will be blocked on one of its outputs when output buffer is flushed. 
Some web sites recommend closing the streams (including STDIN) right a 
way, but there are also reports that it does not always work. See Google 
for more information.

Ps. Please also use exec(String[]) version (or even better - exec(args, 
null, executionDirectory) ), because it will work correctly even if you 
have spaces in paths or arguments.
