Contribution #268. BTW, in the scala 2.3.0 interpreter non of these examples crashes. But the entity is not replaced with what it stands for.

I could not reproduce this bug -- maybe I got the contrib wrong, because I am really writing &amp; (5 letters here). If you had only the ampersand by itself, it would not be wellformed XML.
