Description

I use FOP from within my Gradle build to produce documentation PDFs.

So the VM usually is not closed, but the Gradle Daemon that executes the build stays alive.

I built some PDF and then tried to delete the folder as it was just a test, but one file was still locked by the Gradle process, so FOP seems to leak that file resource.

It was the draft.png that is set as background-image in this snippet.

Also interesting, this page master was not even used, so it is even more suspicious why the file was opened for reading at all, but that it stays locked is pretty unnice.
