Philipp Ottlinger commented on TIKA-4505:
-----------------------------------------
We fixed it on the RAT side as well, thanks. Next release will hopefully work
with newer Tika versions.
> CharsetDetector.getReader returns null when an exception documented

> The CharsetDetector.getReader() javadoc states that it will "Raise an
> exception if no charsets appear to match the input data."
> However, if CharsetDetector.detect() returns null, null is returned from the
> method.
> In addition, if an IOException occurs it is caught and null is returned from
> the method.
> The documentation does not reference null as a possible return value.
> This is the underlying cause of an issue in RAT.
> https://issues.apache.org/jira/browse/RAT-494 where a document is mentioned.
> I have requested access to the document in question, if I get access and have
> permission to distribute the file I will attach it here if you wish.
