Well, yes, there is a danger of deadlocks, but this can be avoided by:
- having separate threads read stdout and stderr
- closing the various streams in the parent (but might cause child to exit)
- using redirectErrorStream
- using new redirection facilities in jdk7 http://download.java.net/jdk7/docs/api/java/lang/ProcessBuilder.html
To be clear, you're saying that if i call this, and allow the parent to be killed (by throwing a Error for instance), the child process lives still? (I believe i can't call System.exit(1) without all jvm dying right?)
Why not try it? System.exit should only cause one jdk to exit directly.
