Hi Shawn, Thank you for your answer. I have solved the problem.
The problem is, in our code constructor of TurkishFilterFactory is setted as protected and that works without problem on the 3.x versions of the Solr but gives the exception that I mentioned here on 4.x versions. By analyzing the stack trace I saw that it gives an InstantationException and by making constructor public solves the problem.
