Get more memory? LOL
I'm responding not with a specific answer but because your
question unfortunately typifies all the problems I've associated
with PDF applications as seen by end users. When an Acrobat
Reader ties up my CPU in an infinite loop or even finite but
extensive processing, or takes
all my memory, the usual response from anyone
on the other side of the fence is " you need more CPU or memory etc,
don't be cheap etc"
Essentially you express surprise that a document of unbounded
size can not be processed and you first tried to fix the problem
the easy way, an approach I myself often take rather than hunt down
a memory leak ( and usually this will limp along for a while).
I guess in this case the strategy is to look for common patterns
or constructs in java that require someone to hold on to references
until there is an explicit call to something like release ( after of
course looking for task/application specific features that
would cause you to buffer everything in memory LOL).
In this case, I just grepped the source code for "memory" and
does look like there are reasonably good comments about this issue
in many places. "Release" is often used and the code is pretty well
written so you can go through and find methods that may use this name,
518 for f in `cat xxx`; do grep " public .*(" "$f" ; done> fff
make a vocabulary list ( again, names are easy to parse mostly ),
522 cat fff | sed -e 's/(.*//' | sed -e 's/public//' | sed -e
's/\([a-z]\)\([A-Z]\)/\1 \2/g' | freqassoc> ggg
or, if you look for "release",
526 cat fff | sed -e 's/(.*//' | sed -e 's/public//' | grep -i release
