A DESCRIPTION OF THE PROBLEM :
write() to an InflatOutputStream after finish() will cause NPE.


---------- BEGIN SOURCE ----------
InflaterOutputStream ios = new InflaterOutputStream(OutputStream.nullOutputStream());
        ios.finish();
        try {
            ios.write(1);
        } catch (Exception e) {
            System.out.println("InflaterOutputStream NPE after finish(): " + e.getClass().getName());
        }
---------- END SOURCE ----------
Expected Behavior:
Per Java's OutputStream convention, after finish() (or close()), further calls to write() should throw an IOException indicating the stream is closed, not an NPE.

Actual Behavior:
Instead, InflaterOutputStream.write() will throw a NullPointerException.
