This is the error:

I have verified that all the jar files are of the same version that is specified in the corenlp.py code, earlier I had used a latest version of it and appropriately updated it in corenlp.py, in either cases, getting the same error. Not able to figure it out, kindly look into this and please suggest a solution.

Got the solution. I was running Java jdk version 9 on my system. Remove it and install jdk 8.
