Hi  
When I run the code, it works. But if I set a breakpoint and run again, Water crashes :

```

Here is a test case :

```
namespace consoleapplication21;
uses
  java.util;
type
  Program = class
  public
    class method Main(args: array of String): Int32;
    begin
      var cp : String := java.net.URLDecoder
                             .decode( typeOf(Program) 
                                      .getProtectionDomain()
                                      .getCodeSource()
                                      .getLocation()
                                      .getPath(),
                                      'UTF-8'
                                    );
      writeLn(cp);
    end;
  end;
end.

```

I’m using the latest stable version.

Reproduced; this seems to be related to the (not officially supported yet) Black theme; workaround will be to switch back to White for now.
