Tilman Hausherr commented on PDFBOX-4836:
-----------------------------------------
RandomAccessReadBuffer(InputStream) creates an empty buffer if the InputStream
is from an URL.openStream() because available() returns 0. I have this on jdk8.
> Reduce the usage of ScatchFileBuffer when parsing a pdf
