Summary

Implement Era.getDisplayName() in each subclass of Era.

Problem

The default implementation of Era.getDisplayName doesn't work with non-IsoChronology because DateTimeFormatterBuilder.TextPrinterParser.format fails to get the Chronology of the Era.

Solution

In each subclass/enum of java.time.chrono.Era, override Era.getDisplayName() and return appropriate display name for the era, depending on its style and locale.

Specification

In java.time.chrono.{Hijrah|ThaiBuddhist|Minguo}Era enums, add the following method:

/**
  * {@inheritDoc}
  *
  * @param style {@inheritDoc}
  * @param locale {@inheritDoc}
  */
@Override
public String getDisplayName(TextStyle style, Locale locale)
