This was deliberate change as FilterOutputStream.close was silently 
ignoring the exception from the flush (a serious bug in my view). In the 
original discussion [1] I noted that we may have to consider a 
compatible switch in the event that it causes problems for applications 
that don't expect close to fail. You may be the first.
