ClearNLP Error: java.lang.NullPointerException at com.googlecode.clearnlp.tokenization.EnglishTokenizer.normalizeNonUTF8

I'm trying to find a good Semantic Role Labeling tool that I can use in my java 
code using Netbeans.
I tried ClearNLP and it work with testing the version with the right output fom 
this link: https://code.google.com/p/clearnlp/wiki/Installation

But when I used the following code:

    }

I got the following error:

I already added all the jar files:

how can I solve this error?
and is there a better SRL that I can use?

Thanks in advance
