Description

Using Apache FOP in a server side application to render thousands of labels. Generally the users request PDF format which works fine but we had reports of malformed content when users requested png or jpeg. Did some local testing and confirmed that this is indeed an issue with the apache fop library. Running through our code in an async manner for pdf's works fine but doing the same for jpeg get's weird results.

Unfortunately I cannot provide the code used but it should be easy to reproduce locally.
