"OutOfMemoryError: Java heap space" even when using MemoryUsageSetting.setupTempFileOnly()

[אור וזהר]

hi

when try to load large pdf files (70000 pages , 70MB size file), I get the
"OutOfMemoryError: Java heap space"

tryed this :



MemoryUsageSetting mus = MemoryUsageSetting.setupTempFileOnly();

PDDocument document = PDDocument.load( file ,mus);



also tryed this :

MemoryUsageSetting mus = MemoryUsageSetting.setupTempFileOnly();

RandomAccessBufferedFileInputStream ra = new
RandomAccessBufferedFileInputStream(file);

document = PDDocument.load( ra ,mus);



but in both cases I get this error :



Exception in thread "main" java.lang.OutOfMemoryError: Java heap space

The following error occurred while executing this line:





looks like MemoryUsageSetting.setupTempFileOnly() has no affect ?

do I use it incorrectlly ?



** I can overcome this problem with -Xmx1500m but had to increase my
physical memory.. , and.., I have much bigger files (250000 pages)…





thanks!
