The javadoc spec for java.util.TimeZone.getDisplayName(*, Locale) does not
specify digits symbols, which are used to represent offset in case of timezone
name is not available for the specified locale ('GMT[-+]hh:mm' format). Some
locales (for example Kanji or Hindi) has own [alternative] digit symbols. The
javadoc should clearly specify whether alternative digit symbols are allowed to
represent digits in the timezone name returned by
TimeZone.getDisplayName(*,Locale).

Following JCK tests are failing due to this problem:
api/java_util/TimeZone/index.html#getDisplayName[TimeZone2009]
api/java_util/TimeZone/index.html#getDisplayName[TimeZone2011]

Below is message from a licensee, showing the problem:
