Not sure if anyone helped you yet (sorry for the slow answer). The
basic punch-line is that the Java <-> C++ bridge is -incredibly- slow,
and as such if we start doing byte-by-byte reading across that interface
life can be horribly awful.
So - in general it would be 1000ish times quicker to stream the file to
disk, and pass a URL to LibreOffice; that sounds like it should be
slower but ... really it will not be; and a short-duration tmp file is
unlikely to hit the disk but float in RAM (though check your permissions
to avoid security issues).
HTH,
Michael.
