Missing dependency pdfbox

[rsoika]

The pom.xml is missing the dependency

        <dependency>
            <groupId>org.apache.pdfbox</groupId>
            <artifactId>pdfbox</artifactId>
            <version>${apache.pdfbox.version}</version>
            <scope>compile</scope>
        </dependency>

This leads into a runtime problem for ocr processing!
