> org.apache.olingo.odata2.core.rest.RestUtil's extractAcceptHeaders is not guarding against an NPE for the missing accept headers. 
> cxf-2.7.x currently returns an empty list in this case, therefore it does not lead to an issue. However, the correct behavior is to return a null in this case.

> Therefore, the above method should guard against an NPE for the acceptHeaders variable being null.
