Guillaume Grossetie commented on CXF-6231:
------------------------------------------
I found the following line in one of our interceptor:
{code:java}
message.getExchange().put(StaxOutInterceptor.FORCE_START_DOCUMENT,
Boolean.TRUE);
{code}
This was the root of the issue... sorry about that, I hope you didn't waste too
many time :)
