I don't have a system Java installed on this VM.

Using the bundled Java, I get the same IOException with this trivial

  package VASSAL.test;

  import java.lang.Process;
  import java.lang.ProcessBuilder;

  public class RunTest {
    public static void main(String[] args) throws Exception {
      final ProcessBuilder pb = new ProcessBuilder("/bin/ls");
      final Process proc = pb.start();

This has no problem listing the contents of the working directory
on Linux.

Is there anywhere one can check if you're running into sandboxing?
Are denials logged? The error message is rubbish if that's what's
