Could you try with either 1.5.6 or 1.6-beta-1, I think this should be working with these versions.

Fails on both 1.5.6 and 1.6-beta-1 (I put a println into the while loop; the word "null" is what appears after it hits end of file.

The readLine() call on the underlying BufferedReader (at least in recent JVMs) just returns null when EOF is reached rather than throwing an exception. So, the doco is wrong in this instance. Wiki updated. Thanks for raising this.
