com.ctc.wstx.exc.WstxParsingException: Received event END_DOCUMENT, instead of 
START_ELEMENT or END_ELEMENT.
org.apache.olingo.odata2.api.ep.EntityProviderException: An exception of type 
'WstxParsingException' occurred.

Note that I am using olingo 2.0.7 library (locally built using source code).
We have 3 environment setup, we have observed this error on one environment. 
When we run our code in debug mode it works fine.
Looks like this error is not constant. Some time it works, sometime 
WstxParsingException is seen.

What could be root cause and how to avoid this error. Any pointer? Please let 
me know.

Thanks in advance.
