The change looks okay. Related is that someone with a reference to the 
underlying InputStream/OutpuStream could close the stream so that the 
channel read/write throw an IOException other than 
AsynchronousCloseException but that isn't something you can solve.

For the test then you might want to break up the really long lines to 
keep it consistent with the rest of the test.
