Description

There seems to be an issue with PDFBox when rendering certain PDF files, when calling renderImageWithDPI; the call seems to hang indefinitely.
My jar file is ruunning with the parameter: -Dsun.java2d.cmm=sun.java2d.cmm.kcms.KcmsServiceProvider

I noticed this issue on this file:[ https://1drv.ms/b/s!Av-Yk52R4YupvcUEZFueSnXFh6_pXw]

Here is the call to renderImageWithDPI:

PDDocument doc = PDDocument.load(file);
PDFRenderer renderer = new PDFRenderer(doc);
BufferedImage img = renderer.renderImageWithDPI(0, 300.0f, ImageType.RGB);

checking the stack trace using jstack gives me the following:

I left my application running over the weekend to see if the call will eventually return, three days later and still the application is at the same spot.
