[9] RFR: 8075173: DateFormat in german locale returns wrong value for month march

[Masayoshi Okutsu]

Hi,

Please review the fix for 8075173. There's an inconsistent month 
abbreviation between the traditional JDK resources and CLDR-derived 
ones. We decided to take the CLDR one, Mär.

Bug report:
https://bugs.openjdk.java.net/browse/JDK-8075173

Thanks,
