json property-names cannot start with numbers

[fries]

I just discovered that json property-names cannot start with a number.
The number 1 could be an ID, weeknumber, etc...
when you try to load something like this

{
"1":[

{ "name": "value"},
{ "name": "value"}]

}

when this scenario occurs an org.apache.commons.jxpath.JXPathInvalidSyntaxException is thrown with the following message: Invalid XPath:'1'

To me this is a rather serious limitation.
