8187649: ArrayIndexOutOfBoundsException in java.util.JapaneseImperialCalendar

[naotoj]

Please review the fix. The issue was informed yesterday by @amaembo that it offends some code analysis tools.
Although the fix is to change the condition error, it turned out that JapaneseImperialCalendar.roll() did not work for WEEK_OF_MONTH and DAY_OF_MONTH. There was an inherent issue where GregorianCalendar does not follow the roll() spec, i.e., "The MONTH must not change when the WEEK_OF_MONTH is rolled." during the Julian/Gregorian transition. JDK-6191841 seems to have tried to fix it but it was closed as Future Project...
So I simply fixed the roll() issue in JapaneseImperialCalendar to follow the spec here, which seems to be the intent of the original author.
