';' is only allowed in block expressions

public class Foo {
  public String foo() {
     if(1>2) return "foo";
     else return "bar";
    }
}

Will be converted to 

class Foo {
  def foo(){
    if (1 > 2)     return 'foo';
 else     return 'bar';
  }
}

which has syntax errors, as the ';' are only allowed within block epressions
