Switched to GeoTools 8.7
Fixed Content is not allowed in prolog errors

Before this fix, it was always tried to parse LiteralData as XMLObject.
This caused the above exception (in the log it is declared as "Fatal
error"). All tests run through, is there a situation thinkable, where
the parsing is actually needed? Literal XML values maybe?

Switched to GeoTools 8.7.
Test class for OutputDataItem

This class is for testing the updateResponseForLiteralData() method of
the class OutputDataItem.java. You will see that while creating each of
the currently supported LiteralDataBinding-outputs the message: "[Fatal
Error] :1:1: Content is not allowed in prolog." is logged. This happens
because it is tried to parse the literal data values as a XMLObject. Do
you see situations, in which the parsing actually makes sense? XML in
literal string outputs perhaps? Otherwise, I would have a fix
ready,which would be my next pull request.
