Hello.
I have a multi-threaded solution: one provider sets data on a queue and N consumers dequeue the data and render PDF reports.
In every ~2000 reports there are up to 3 reports with no logo, displaying "Current report item is not supported in this report format" in its place.
It occurred a whole lot more (1 out of ~100) earlier, when all threads used the same template and image files. After creating a specific work space for each thread, it happened less (1 every ~350 reports). Then I started reloading image data for each report and reduced it to the present ratio.
Any help would be much appreciated; technical details are below.

The image reloading java code is:
byte[] imageData = getBytes(new File(theLogoFile));
EmbeddedImage embeddedImage = reportDesign.findImage(logoPlaceholderName);
embeddedImage.setData(imageData);
imageData = null;
