Hello,

I have a PDF document that produces the following stack trace :

{code:java}
INFO: OpenType Layout tables used in font FreeSans are not implemented in PDFBox and will be ignored
Exception in thread "Thread-1" java.lang.IllegalStateException: Expected 'Page' but found COSName{Font}
	at org.apache.pdfbox.pdmodel.PDPageTree.sanitizeType(PDPageTree.java:227)
	at org.apache.pdfbox.pdmodel.PDPageTree.access$300(PDPageTree.java:38)
	at org.apache.pdfbox.pdmodel.PDPageTree$PageIterator.next(PDPageTree.java:189)
	at org.apache.pdfbox.pdmodel.PDPageTree$PageIterator.next(PDPageTree.java:153)

	at org.apache.pdfbox.text.PDFTextStripper.getText(PDFTextStripper.java:227)
{code}

I found a similar problem here https://mail-archives.apache.org/mod_mbox/pdfbox-users/201610.mbox/%3C2e858989-2fb9-d000-5320-b644fcc71f81@t-online.de%3E

So, I understand that the problem comes from the pdf itself but given that some readers recover from it, is there any plan to add some recovery methods in PdfBox too?

Thanks
