This will break the java wrapper. Change [FormFactorPropertyGenerator.java#L37](https://github.com/ArcBees/GWTP/blob/master/gwtp-core/gwtp-mvp-client/src/main/java/com/gwtplatform/mvp/rebind/linker/FormFactorPropertyGenerator.java#L37) to:
```java
private static final String OUTPUT = "{\n%s\nreturn findFormFactor('%s', location, navigator);\n}";
```
