------------------------------------------------------------------
I need some time to review the effects with different jdks and different
configurations (KCMS / LCMS). I ran a rendering diff test and the rendering of
8 files of 1000 are different. One of them was known to have bad rendering
(PDFBOX-2917) and that looks good now, so this is getting interesting :)
Shouldn't {{fixProfile}} be called *after* {{is_sRGB}}?
And what if java has fixed this bug in some later version - wouldn't your fix
"undo" it?
Your parameter is named "cmykProfile" but ICC profiles don't have to be CMYK.
There can be with 3 colors or gray (PDFBOX-1274).
Please edit your question to add what you've found "across internet", i.e. put
a link or two there.

> colors, like semitransparent white plane covering the page
> See the render output
> Looking across internet I've found that this issue is caused because JSK has
