Hi,
Is the pdf you are reading a single file that is 1.5gb? If so, I guess you
should try doing this in multiple passes. You should read 6.1.2 of iText
second edition. Simply, read the first acceptable number of pages and on the
second run read that many more starting where you left.
You might also try providing BufferedInputStream to PdfReader which should
not be reading the whole file into memory but this may possibly be slower if
PdfReader needs to access file randomly.
If you have the issue when writing the pdf as well, then I would ask if you
are keeping the output stream in memory until pdf is finished when writing
to disk. If so, you should avoid doing that or reserve that much of memory
to JVM.
Good luck
