org.n52.oxf.OXFException: Could not parse response to XML

It's not easy reproducing it, but it seems that sometimes there is an attempt to read the xml reply before it's ready.

Maybe it can help: Apache Commons IO released v1.4 which includes an AutoCloseInputStream wrapper which cleans up InputStreams once they have been read.
