Hi,

Parsing an excrypted PDF Document is causing ES to crash after a few attempts. Below is some followup exceptions because of the main cause.  
org.apache.pdfbox.pdfparser.XrefTrailerResolver] Did not found XRef object at specified startxref position 0

Is there a workaround for this. Can we make to avoid such files?

I think you are using mapper attachments plugin, do you?  
If so, can you open an issue in the project repo and provide details such as:

- version (es and plugin)
- a link to a failing file

We have [a unit test](https://github.com/elastic/elasticsearch-mapper-attachments/blob/master/src/test/java/org/elasticsearch/index/mapper/attachment/test/unit/EncryptedDocMapperTest.java) for that so I'd like to understand what is happening here.

Thanks

yes we are using mapper plugin.

Plugin version is 2.5 and ES version is 1.5.2. For policy reasons I cannot share the customer file with you. Trying to see if I can repro with some corrupt file.

Opened issue - Mapper Plugin crashes ES when corrupt file. Msg Document is encrypted #160

I need a file which helps to reproduce.  
Also consider upgrading and test again the same file.
