NullPointerException in tika-app, parsing PDF content
-----------------------------------------------------
Key: TIKA-778
URL: https://issues.apache.org/jira/browse/TIKA-778
Project: Tika
Issue Type: Bug
Components: gui, parser
Affects Versions: 1.0
Reporter: Bastian Mathes
I try to extract text from some pdf files with the tika app. In version 0.10
the error
ERROR - Error: Could not parse predefined CMAP file for '--UCS2'
is printed on the command line, but text extraction works and is correct.
In version 1.0 I get the same error message on the command line, but also
receive an exception and no text is extracted:

I tried the same pdf files (and can switch forth and back between version 0.10
and 1.0, this behavior is stable) and it looks like the exact same pdfbox
version is inside the tika-app-0.10.jar and tika-app-1.0.jar. It would be great
if version 1.0 could do what 0.10 can. Sorry that I cannot provide the pdf.
