RFR 8185719 [testlibrary] : RMI TestSocketFactory does not flush

I wonder if the MatchReplaceOutputStream should store the
partial match index at the time the partial bytes are flushed
in order to verify that this was indeed a partial match,
and report an error if it later finds that flush() was indeed
called during a full match? The potential Error to throw could
be created and recorded in flush() in order to diagnose
the offending flush() call...
On the other hand to do this properly you'd probably need
to maintain a stack of partial match indexes and corresponding
potential Errors to throw in case flush() is called again with
a partial match while the previous partial matching hasn't
been invalidated yet...
I mean - if your matched bytes are stg like 0 0 0 6
and the stream looks like:
3 0 0 <flush> 0 <flush> ...
then either 6 or 0 0 6 coming after the second flush would
make the test fail to find & replace the full match...
But maybe it's not worth it if you are sure that flush() cannot
be called during a full match/replace sequence?
