------------------------------------
Summary: External file links in PPTX misparsed
Key: TIKA-2136
URL: https://issues.apache.org/jira/browse/TIKA-2136
Project: Tika
Issue Type: Bug
Components: parser
Affects Versions: 1.13
Environment: Windows 7 x64, JVM 1.8.0_101
Reporter: Seva Alekseyev
Attachments: 81809 lab presentation.pptx
The attached document contains links to external files. Trying to parse it with
the Tika parser throws the following error:
java.lang.NullPointerException

The error happens in the URI validator, but not because the URI fails
validation; the function fails because partURI.getPath() returns a null and
there's no null check. The link in the file may not be valid, but it's not
malformed. And it definitely shouldn't prevent text extraction from the file.
