OfficeParser can not detect embedded zip bomb in the office documents

Hi, I am trying to get "zip bomb detection" exception but I can't. I used attachments as below and I saw this situation like that:

When I send "zipbomb.xls" and "zipbomb.doc" to Tika, Tika threw exception.

When I send "zipbomb.xlsx","zipbomb.docx","zipbomb.ppt" and "zipbomb.pptx" to Tika, Tika didn't throw exception.

Thanks.
