Hello Naoto,

As far as I can see, the testMap cannot be used to test the day period strings. More specifically, consider this change (git diff) that I did as you suggested (unless I misunderstood what you meant):


+        testMap(US, AM_PM, ALL_STYLES,
+                "AM",
+                "PM",
+                "midnight",
+                "noon",
+                "in the morning",
+                "",
+                "in the afternoon",
+                "",
+                "in the evening",
+                "",
+                "at night",
+                "",
+                RESET_INDEX,
+                "a", "p", "mi", "n", "", "", "", "", "", "", "", "");
+        testMap(US, AM_PM, ALL_STYLES,
+                "AM", "PM",
+                RESET_INDEX,
+                "a", "p");



This will fail with the following error.

testMap: locale=en_US, field=9, style=0, expected={in the afternoon=6, in the evening=8, in the morning=4, at night=10, midnight=2, noon=3, AM=0, PM=1, mi=2, a=0, n=3, p=1}, got={AM=0, PM=1, a=0, p=1}
java.lang.RuntimeException: test failed


That failure is due to the `testMap` method expecting these day period string to be part of the returned Map from `Calendar.getDisplayNames()` which won't be the case because that API (as per the javadoc) will only return a Map whose display names have valid field values, so in this case only those display names which will have `AM` or `PM` as a value.

If it's easier to review, I will go ahead and push the suggested change in this testcase and let if fail so that you can get a chance to look at the actual test code and error. Let me know.
