John Mastarone commented on TIKA-853:
-------------------------------------
I made my own version of the IsoBufferWrapperImpl in which the ByteBuffer array
is public, and I tried using the sun.misc.Cleaner code from the bug page in
your link on each element in the ByteBuffer array, and following it with a call
to tstream.close() (which causes my IOException). I tried putting this block
right after the call to isoFile.parse(), and separately tried putting it at the
end of the Tika MP4Parser's parse method; neither case prevented the exception
from occurring. So, maybe Jukka's suggestion of using deleteOnExit() is the
easiest solution for the moment...
