On linux (debian), I can run this command:

```
/usr/lib/jvm/jdk1.7.0_21/bin/java -jar ~/myjar.jar ".*"

```

I am trying to run it from a Java program instead with:

```
ProcessBuilder pb = new ProcessBuilder(java, "-jar", "~/myjar.jar", "\".*\"");

```

`System.out.println(pb.command());` prints the following, as expected:

```
[/usr/lib/jvm/jdk1.7.0_21/bin/java, -jar, ~/myjar.jar, ".*"]

```

However I don't get the same output from the program (it runs but the ouput looks as if the `".*"` argument is not properly taken into account).

Any ideas why it doesn't work?

*Note: the same code works fine on Windows.*
