addMonthsToSameDay : behaving different for 30 and 31 st Dates

addMonthsToSameDay function is behaving differently(as far as I think) for the 30 & 31 st of the months. Please, check the below table:

addMonthsToSameDay(java.lang.String theDate, int numOfMonths)

For 30 & 31 st, Its skipping the immediate next month and giving a different output than expected.

Could you please answer, why its behaving differently for 30 & 31.

We are passing numOfMonths as 1.
