Description

To determine ModuleLocation, replaceAll is used on File.separator, which is "" on Windows systems.
mystring.replaceAll(String.valueOf(File.separatorChar), ".")
replaceAll is expecting a regex to replace, but "" is a reserved character in regex. An error is thrown:
java.util.regex.PatternSyntaxException: Unescaped trailing backslash near index 1

If you just replace all occurrences of .replaceAll(String.valueOf(File.separatorChar) with replace(File.separatorChar, '.'), it will work.
