You can verify this by comparing the results of `java -version > /dev/null` and `java -version 2> /dev/null` in a shell. Some programs choose to print their version to standard output, e.g. `go version`. Output() returns the process's standard output and possibly an error, but it does not give you the process's standard error. CombinedOutput should give you both streams combined, or you could fiddle with StderrPipe and StdoutPipe.
