NetBeans java.time code completion: missing zone ID list

Goal

To enable automatic completion of all available ZoneId identifiers when invoking ZonedDateTime.now(ZoneId.of("…")) in NetBeans.

Constraints & Uncertainty

NetBeans’ built‑in code completion currently offers only a limited set of zone IDs. Developers must type zone identifiers manually, which is error‑prone for large or uncommon zones. It is unclear whether this behavior is intentional, configurable, or dependent on JDK version or project settings.

Open Questions

• Does NetBeans provide a setting or preference to extend the zone‑ID completion list to include all IDs from ZoneId.getAvailableZoneIds()?
• Can a plugin or external completion provider be integrated to supply the full zone‑ID list without manual typing?
• Is there a documented limitation in NetBeans regarding java.time completion that would explain this omission?
