I have answered all the questions. I believe KCMS property is not helping much too, I just tried and the result is same. Please check the output file. I have updated it with sysout of those properties at the top.
Thanks Tilman for responding.

I have already read FAQ yesterday itself. I will try rest of the options and post it here today itself.
> Memory Leak while converting pdf to images
> ------------------------------------------
>
> Key: PDFBOX-4041
> URL: https://issues.apache.org/jira/browse/PDFBOX-4041
> Project: PDFBox
> Issue Type: Bug
> Affects Versions: 2.0.7
> Reporter: Ajit
> Attachments: File2_5Mb.pdf, PDFConverter.java, heap.jpg, output.txt
>
>
> I am observing memory leak in PDF to images conversion simple program. I realise the PDF that I am converting is bit bigger in size.
> Check the heap image and you will see that leak is happening even though I have flushed the buffered image and set it to null explicitly. I have also closed the document too.
> !heap.jpg|thumbnail! If you notice the image, the process was running at 2 GBs in only two runs. I am not able to attach the heap, because of its bigger size. But note the image at the bottom and you will see that BufferedImage is taking about 500 MBs.
> I have also provided the source code (few lines) and hoping I haven't done any stupid mistake.
> * I have gone through getting started [https://pdfbox.apache.org/2.0/getting-started.html] and set -Dsun.java2d.cmm=sun.java2d.cmm.kcms.KcmsServiceProvider -Dorg.apache.pdfbox.rendering.UsePureJavaCMYKConversion=true the options. It does not help much
> * Maven Dependencies - pdfbox-tools, jai-imageio-core, jai-imageio-jpeg2000, levigo-jbig2-imageio
> There are some debug messages related to ScratchBuffer, I searched about it and it seems it is harmless. I came across the bug PDFBOX-3388. From the comments, It seems it is relevant but harmless.
