---------------------------------------
Oh, now that I've slept, I realize it can be null if /Encoding is null.

> Key: TIKA-3847
> URL: https://issues.apache.org/jira/browse/TIKA-3847
> Project: Tika
> Issue Type: Bug
> Components: parser
> Affects Versions: 2.4.1
> Reporter: Yurii
> Priority: Major

>
>
> I have a pdf document with some corrupted pages(throws error even in PDF
> readers like adobe acrobat). However there are only few pages of 370 are
> failing.
> The issue is that first corrupted page is 15th and whole document processing
> failed after that.
> There is a nullPointer exception thrown on getting fonts of the corrupted
> page.
> What I propose is to allow(by config, default false) handle any runtime
> exception like we do for IntermediaryIOExceptions.
> Unfortunately due to NDA I can't share a document for debug purposes but here
> is a stacktrace below:
> {code:java}
> java.lang.NullPointerException
