ModbusNumberException for valid value

[kkieffer]

I encountered a strange error which seemed like it cannot occur. This is in version 1.2.9.2. Stack trace below. I get a ModbusNumberException for value "4112". However in WriteSingleRegisterResponse.setValue, the value is first cast to a short and and'ed with 0xffff. Then the checkValue makes sure its within the range 0 to 65535. Clearly 4112 passes that check so I can't understand why the exception is being thrown.
