Hello,

We are facing a problem while reading large Pdf files (around above 32
Meg with 5000 pages).
I am using itext-5.3.0 System configuration = Solaris with
Weblogic-9.2 and JVM HotSpot

I tried bellow constuctors to read the Pdf

1. PdfReader(byte[] pdfIn)
2. PdfReader(RandomAccessFileOrArray raf, byte[] ownerPassword)
3. PdfReader(String filename)

But all of above stuck when Pdf is larger than 32 Meg

java.lang.StackOverflowError
        at java.util.HashMap$KeySet.iterator(HashMap.java:867)
        at com.lowagie.text.pdf.PdfReader.removeUnusedNode(Unknown Source)
        at com.lowagie.text.pdf.PdfReader.removeUnusedNode(Unknown Source)
        at com.lowagie.text.pdf.PdfReader.removeUnusedNode(Unknown Source)

Within my  application, i have a servlet which reads pdf file and
write to out-put stream. I have an intermediate Servlet Wrapper which
wraps this output-stream and pass data to PdfReader. Bellow are
alternative methods which i tried but unfortunatly each of them cause
same exception error.

Method 1: PdfReader(byte[] pdfIn)
--------------
PdfReader reader;
reader = new PdfReader(pdfWrapper.getData());
========================================

Method 2: PdfReader(RandomAccessFileOrArray raf, byte[] ownerPassword)
--------------
PdfReader reader;
RandomAccessFileOrArray raFileOrArray = new
RandomAccessFileOrArray(pdfWrapper.getData());
reader = new PdfReader(raFileOrArray, null);
========================================

Method 3:PdfReader(String filename)
--------------
PdfReader reader;
reader = new PdfReader("/tmp/large-file.pdf"); // this path has rw permission.
========================================

We also changed JVM Memory setting to...

-Xms2048m -Xmx4096m -XX:PermSize=512m -XX:MaxPermSize2048m
-XX:ThreadStackSize=512


So please help me out in this.

Regards,
Hanmant.
