When creating the multi-file schema tests, I was working through a failing test, filling in properties as the runner complained that they were missing. I got to a point where this was my error:

Note that the error listed in gray "Schema Definition Error: Property ignoreCase is not defined" is not propagated through to the red error text, and instead an empty exception is displayed. I have only seen this issue with the ignoreCase property. See test double_nesting_01 in
