Yes you're right and its a shame I didn't think of it at the time.

However, any break in binary compatibility will force a package rename for IO here in commons. So until that happens, this change can't.

> In the Java specs for [*java.io.Reader.close()*|http://java.sun.com/j2se/1.5.0/docs/api/java/io/Reader.html#close()], it states
> {panel}
> Once a stream has been closed, further read(), ready(), mark(), or reset() invocations will throw an IOException
> {panel}
> However, the *org.apache.commons.io.input.CharSequenceReader* does not do this, but instead resets the file back to the start when it is closed. This causes problems when passing this reader to some libraries (albeit admittedly poorly written ones) that rely on *read* throwing an *IOException* after the reader has been closed.
