Description

gagravarr noticed that one of our old test files fails a Tika test now with PDFBox 1.8.7 and Java 1.6.

I just tested the pure PDFBox app built with PDFBox 1.8.8-SNAPSHOT, and I'm getting the same exception with Java 1.6 and Java 1.7.

Stacktrace:

ExtractText failed with the following exception:
