Hello, I wanted to report another common issue I am encountering during my research. For instance, while parsing https://github.com/stanfordnlp/CoreNLP/commit/b95cd18ce7e865bcb7cc3f3ade2c2e08295c6d6f using Spoon as a library, I get this error:

Thanks for the bug report. Would you be able to write a failing test case in a pull-request? That would be super useful.
