Solr ExtractingRequestHandler pdf text extraction

I've a problem with the pdf text extraction of Solr. Solr uses Apache Tika for extracting the text of a PDF file and tika uses PDFBox for that. When I send my PDF file to Solr it extracts the text successfully, but the text is totally messed up. Something like that

MonaPersNr.KSt.KUZKapaz.Sollstd.MonatJahrtsbericht

But when I extract the same PDF file directly with PDFBox at the command line with following command I'll get a nice result.

java -jar pdfbox-app-1.6.0.jar ExtractText -console test.pdf

I don't know which Tika version or better which PDFBox version is used by solr. I even can't find the library for that in the solr war file... All libs in the lib dir are the following:

I would be really really happy if somebody knows a solution for that.

Solr holds the additional jars for Tika and its dependencies in a separate folder, which are not packaged as a part of the Solr deployable.

For Solr 3.4 -

If you have the solr trunk, the jars can be seen in the solr/contrib/extraction/lib folder

On the subversion you can find the jars @ path which is pdfbox-1.3.1.jar

The trunk for Solr has the latest pdfbox-1.6.0.jar.
