Description

If reference value passed to EscapeReference.referenceInsert(String reference, Object value) is null,
then derived clases produce NPE when trying to do toString()

This condition shall be guarded like this: ( insert it on line 86 - too trivial for a patch )
if(value == null)
return value;
