[TYPO3-Solr] solrfal tika error with scheduler

[Robert W]

Hello,

When running solr, solrfal, fal_securedownload locally manually starting the scheduler, documents are indexed and there are no errors thrown. In running solr and solrfal locally, starting the scheduler from the command line, solr runs without errors. Solrfal throws the following error:

Fatal error: Class 'ApacheSolrForTypo3\Tika\Slots\RuntimeException' not found in C:\Daten\arbeit\www\typo3_6\typo3conf\ext\tika\Classes\Slots\TextExtractor.php on line 77

In looking at the code, I am not sure why this is happening as it functions properly when the scheduler is run mannually. The document is of type "docx" which is a type allowed by the textExtract services running in the TYPO3 backend. 

Has someone experienced this error before or can provide the solution how to resolve this?

Thank you,
Robert
