TikaServer not initializing properly

[Subhajit Das]

I am getting this in console out:
org.apache.tika.config.InitializableProblemHandler$3 handleInitializableProblem
But nothing on logs.

When a /tika put is send for PDF, I get nullpointer exception in 
AbstractPDF2XHTML.java in line 434.

Using Tikaconfig:

<?xml version="1.0" encoding="UTF-8"?>
<properties>
  <service-loader loadErrorHandler="WARN"/>
  <parsers>
    <parser class="org.apache.tika.parser.pdf.PDFParser">
      <params>
        <param name="ocrStrategy" type="string">ocr_only</param>
        <param name="ocrImageType" type="string">rgb</param>
        <param name="ocrDPI" type="int">300</param>
      </params>
    </parser>
  </parsers>
</properties>
