     http://download.icu-project.org/files/icu4j/51.1/
2. Create ext directory and put downloaded files into ext directory

3. Compile and run testcase (the test case is in "Source code section" with following options
   $ java -Djava.ext.dirs=$PWD/ext -Djava.locale.providers=CLDR NumberFormatTest



EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
No exception is thrown.
ACTUAL -
