Subject Re: Upgrading guava ?
Date Thu, 23 Feb 2017 07:48:27 GMT
Hi Sean,

Thank you for your answer.

I now use my little cTakes pipeline with guava 18.0 and I get any errors.
Let's note that my pipeline is for now very "basic" : I just launch a
pipeline based on the AggregatePlaintextUMLSProcessor.xml file, so I'm not
using so much third party dependencies at this point.

Thanks again,
