JsonDataException

Thrown when the data in a JSON document doesn't match the data expected by the caller. For example, suppose the application expects a boolean but the JSON document contains a string. When the call to nextBoolean is made, a JsonDataException is thrown.

Exceptions of this type should be fixed by either changing the application code to accept the unexpected JSON, or by changing the JSON to conform to the application's expectations.

This exception may also be triggered if a document's nesting exceeds 31 levels. This depth is sufficient for all practical applications, but shallow enough to avoid uglier failures like StackOverflowError.
