Java(TM) SE Runtime Environment (build 1.8.0_40-b25)

ADDITIONAL OS VERSION INFORMATION :
OSX Yosemite 10.10.2

A DESCRIPTION OF THE PROBLEM :
The output of DateFormat is incorrect in the long form for Finnish, in that it adds an extra 'ta' to the end of the month name.

java8 output:
6. maaliskuutata 2015

java7 output:
6. maaliskuuta 2015

According to wiki language rules for finland, month should end in 'ta': http://en.wikipedia.org/wiki/Date_and_time_notation_in_Finland

"In Finnish a period is placed after the day to indicate an ordinal: ���31. toukokuuta 2002���; furthermore, the month is in the partitive case, always marked by -ta."
