问题
Use process = Runtime.getRuntime.exec("other.sh") to lauch other.sh who exits with 1, however, process.waitFor() returns with 0. Under Linux RedHat 7.
other.sh just starts another Java process that returns by System.exit(1).
I've seen the same problem in https://coderanch.com/t/326568/java/exitValue-returns-inconsistent-values. However, it said that this was a JDK bug in 1.4 and was fixed already. However, I am using JDK 1.8.
I just want to know if there are any other possibilities leading to such weird behavior? Now our customer and we are both frustrated with this incredible issue.
