Nick Burch commented on TIKA-1388:
----------------------------------
Not sure how this is a Buffer Overflow? The buffer is increased in size as
needed, so it's never possible to write past the end of it
Is this problem in the context of a specific parser or file? The likely fix may
instead be in that parser, rather than in the IO Utils
> Tika IOUtils java.lang.OutOfMemoryError
