[9] RFR of 8042377: BufferedWriter and FilteredOutputStream.close throw IAE if flush and close throw equal exceptions

[Brian Burkhalter]

The intent here was to fix a specific problem of exception throwing in close(). Prior to this, re-closing the stream was “protected” by double checked locking. Extending coverage of synchronicity problems to the rest of the class could be addressed in the context of another issue, yet to be filed, should this be deemed desirable.

To be pedantic, what's to prevent close (being called on a different thread from one that allocated the filtered output stream) from seeing inconsistent out field values (assume the stream was published unsafely)? Readers/maintainers of this class may question why this sole bit is covered via an atomic but rest of class isn't.
