Hi Nicolas,

I'm experiencing the following exception when trying to render a PDF:

I believe this issue is more to do with the Flying Saucer transformer then the play-pdf plugin. In fact I think it is this issue which is fixed by this pull request. I'm trying to work out how I get this fix all the way back in to my play app. Is it the case that the Flying Saucer transformer is included via the YaHP project? So will I have to update and build Flying Saucer, then YaHP and then play-pdf? Any assistance appreciated.

cheers,
Chris

Hi @tazmaniax

did you find a way to fix this issue? I'm also encountering this issue. I tried updating the 3rd party libs but it doesn't work.

This fix philcali/flyingsaucer@e653850 with rebuilt jar actually solves the problem.
