> JacksonParser tests for infinite and NaN values in a way that is not supported by the underlying float/double parser. For example, the input string is always lowercased to check for {{-Infinity}} but the parser only supports titlecased values. So a {{-infinitY}} will pass the test but fail with a {{NumberFormatException}} when parsing. This exception is not caught anywhere and the task ends up failing.
> A related issue is that the code checks for {{Inf}} but the parser only supports the long form of {{Infinity}}.
