Environment Details

• Helidon Version: 2.0.0-M3
• Helidon MP (most likely in SE as well)

---

GraalVM 20.0

Problem Description

Compiled MP native image from quickstart. When invoking health, always DOWN.
Result:

{"outcome":"DOWN","status":"DOWN","checks":[{"name":"deadlock","state":"DOWN","status":"DOWN"}]}

[tomas-langer]

Used CLI to create and build the project.

Fixed HealthSupport builder that used Set instead of a List.
Changed Deadlock to send UP in native-image always.
Tested with Hotspot and Native image.
