Tilman Hausherr commented on PDFBOX-2988:
-----------------------------------------

This is on page 8. XObject XO4 has a resource that has an XObject XO4.
{{Root/Pages/Kids/\[1]/Kids/\[1]/Resources/XObject/Fm3/Resources/XObject/Im7/Resources/XObject/XO4/Resources/XObject/XO4}}

I'll add a check to avoid recursion.

> On TIKA-1742, [~nated] reported that a particular PDF causes an infinite 
> recursion/stack overflow while trying to extract images.

> ExtractImages.
