Can I please get a review for this proposed fix for https://bugs.openjdk.java.net/browse/JDK-8262108?
As noted in a comment in that issue, the bug relates to the return value of `Calendar.getDisplayNames` for the `Calendar.AM_PM` field. The implementation has started returning invalid values for the `AM_PM` field after the "day period" support was added recently in the JDK as part of https://bugs.openjdk.java.net/browse/JDK-8262108.
The commit here adds a check in the internal implementation of the display name handling logic, to special case the `AM_PM` field and properly convert the display name array indexes (which is an internal detail) to valid values that represent the `AM_PM` calendar field.
The commit also has a new jtreg test case `CalendarDisplayNamesTest` reproduces this issue and verifies the fix.
After this fix was introduced, I ran the test in `test/jdk/java/util/Calendar/` and that showed up a failure in an existing test case `NarrowNamesTest`. Looking at that test case, IMO, the current testing in that `NarrowNamesTest` is incorrect and is probably what hid this issue in the first place? To fix this, I have added an additional commit which updates this test case to properly test the `AM_PM` field values.
