Corpus Creator execution fails

I’m trying out the N-gram Extractor node as an alternative to the Ngram Creator (for reasons articulated here) and was hoping that the Corpus Creator node would perform as per its description, but it just returns an error:

Execute failed: (“ArrayIndexOutOfBoundsException”): null

In any case, I can use other nodes to calculate the frequencies of the extracted ngrams, but I thought I’d raise this in case there’s a bug in the Corpus Creator node.

You’ll need to provide data example, @qqilihq can check the issue.
