Kevin Duling commented on GEODE-2294:
-------------------------------------
I've tracked the problem down to a PrintWriter attempting to deliver the entire
stacktrace in the response. However, only the first 1500 bytes or so are sent,
cutting the message off. Because the response is not set as a multi-part
response and because returning an entire stacktrace as a HTTP response seems
wrong, I've removed the stacktrace from the message. This allows the framework
to generate a well-formed JSON response.
Now the error message will come through and more information can be found by
reviewing the server log.
