John Hewson commented on PDFBOX-3442:
-------------------------------------
Yeah that's what I had in mind. Looking at it now though I wonder if maybe we
should take a hybrid of the two approaches, i.e. storing the direct cache in
PDResources but using SoftReference. Given that there's no point caching the
font beyond the lifetime of the PDResources that created it, and the fact that
SoftReference in this case is essentially the behaviour that everyone wants.
That way we keep PDResourceCache for resources shared across pages only.
