Tilman Hausherr commented on PDFBOX-4084:
-----------------------------------------
I'll fix the classcastexception, but the first file is broken. Here's object 38:
{code}
38 0 obj
<</Annots 64 0 R/Contents 88 0 R/CropBox [0 0 595.22 842]/MediaBox [0 0 595.22
842]/Parent 33 0 R/Resources <</ExtGState <</GS2 93 0 R/GS3 94 0 R>>/Font <</F1
87 0 R/TT10 51 0 R/TT2 40 0 R/TT4 41 0 R/TT6 42 0 R/TT8 49 0 R>>/ProcSet [/PDF

R/X2 90 0 R>>>>/Rotate 0/Thumb 103 0 R/Type /Page>>
endobj
{code}
The object 64 exists twice in the PDF. Once as annotation array, once as font.
Yes there is a specification (compressed object streams) to store things as a
stream, but this is not new and we support it.
What is with the second file? "This also happens in getPages or something else
(See the second attachment)." Is this the same issue?
