Unable to load map with libtiled-java

Nobody has claimed this yet.

The following code is not working for me

``` java
final TMXMapReader reader = new TMXMapReader();
final InputStream stream = this.class.getClassLoader().getResourceAsStream("maps/level_1.tmx");
final Map map;
try {
map = reader.readMap(stream);
} catch (Exception e) {
e.printStackTrace();
}
```

I am getting the following error:

```

I have already verified the stream is loading correctly. What am I doing wrong here?

Also, here is the source of the file I am trying to load:

``` xml

```

Start by reproducing the Java snippet with TMXMapReader.readMap and inspect the resource stream and TMX file shown in the report. Then trace the parser entry point named in the stack trace, tiled.io.TMXMapReader.unmarshal. Done means the reported map loads without the SAX prolog error and the cause is documented or reproducible.
