We're seeing this error (actually a WARN) in our UA log on a Workflow, and wasn't sure if it's anything to worry about:

2016-02-22 08:29:58,976 WARN [org.apache.commons.httpclient.HttpMethodBase] (http-0.0.0.0-8180-6) Going to buffer response body of large or unknown size. Using getResponseBodyAsStream instead is recommended.


This is UA 4.0.2 RBPM module, running on SLES.
