I have the same question that was posted 2 years ago here:
On that page, SahelSoft says they found an answer:
"I solved this problem. The problem was the conflict between stanford parser package and stanford coreNLP package in my workspace."
They don't really say what the answer is. I am new to Java and I trouble figuring out what it would mean to have a conflict between 2 packages. Can anyone offer any enlightenment?
The actual error looks like this:
