Re: Stored Properties file gets emptied

It seems there is a bug with our XMPP client (Java 1.6, smack) - I store
the users settings in a Properties file. My boss tells me on some
customers PCs the settings file sometimes ends up losing the contents.

The class is instanciated in the application at start up with
private static final String APP_HOME =
System.getProperties().getProperty("appdir");
private static final String USER_HOME =
System.getProperties().getProperty("user.home");
private static final String USER_APP_HOME = USER_HOME + "/op3mi";

These seem a little odd. If you're using the two-argument File
constructors, while bother inserting a separator? (Actually, I prefer
to handle paths this way than to access file.separator or similar.)
The docs say that an absolute child argument (the second one) will be
converted in a system-dependent way, so while the leading '/' seems
benign on my system (testing with the program below), it might be
different on yours or your customers'.
import java.io.*;
public class Subfile {
public static void main(String[] args) {
System.out.println(new File(args[0], args[1]));
}
}
