A DESCRIPTION OF THE PROBLEM :
If a DecimalFormat with a rounding mode other than HALF_EVEN is serialized and again deserialized, the rounding mode in the format itself is still the old one,
but the rounding mode which is used is located in the digitList, and that is reset to the initial value HALF_EVEN.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Build a DecimalFormat with a rounding mode other than HALF_EVEN.
Serialize and again deserialize this format.
After deserialization, the rounding mode in the format itself is still the old one,
but the rounding mode which is used is located in the digitList, and that is reset to the initial value HALF_EVEN.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
After deserialization, also the runding mode in the digitList shall be the same.
ACTUAL -
After deserialization, the rounding mode in the format itself is still the old one,
but the rounding mode which is used is located in the digitList, and that is reset to the initial value HALF_EVEN.

REPRODUCIBILITY :
This bug can be reproduced always.
