A DESCRIPTION OF THE PROBLEM :
https://docs.oracle.com/javase/8/docs/api/java/io/FilterOutputStream.html#write-byte:A-int-int-
The write(byte[] b, int off, int len) method documentation states:
Note that this method does not call the write method of its underlying input stream with the same arguments. Subclasses of FilterOutputStream should provide a more efficient implementation of this method.

FilterOutputStream has an underlying OUTPUT stream, not an underlying INPUT stream.
