------------------------------------
My problem was, that I was adding some images and then reading xobjects from
page's resources. This gave me an exception:
Exception in thread "main" java.lang.ClassCastException:
java.awt.image.DataBufferInt cannot be cast to java.awt.image.DataBufferByte

It took me a half day to track the cause down to that single line ;)
But I like brain teasers ;)
