[carlesarnal]

Parent Feature

Part of #6998 - Full AsyncAPI 3.0 Specification Support

Description

Upgrade the AsyncAPI parser library to support AsyncAPI 3.0 specifications. This is a quick-win task that enables basic 3.0 support.

Current State

• Apicurio currently uses AsyncAPI parser for 2.x
• AsyncAPI 3.0 has breaking changes from 2.x
• Need to handle both versions

Scope

Upgrade Tasks

1. Dependency Update

   • Update AsyncAPI parser library to latest version
   • Resolve any dependency conflicts

2. Version Detection

   • Detect AsyncAPI version from spec
   • Route to appropriate parser

3. Basic Validation

   • Validate 3.0 structure
   • Ensure 2.x specs continue to work

Out of Scope (for this task)

• CloudEvents bindings
• Protocol binding validation
• UI changes for 3.0 features

Implementation Steps

1. Check current AsyncAPI parser version in pom.xml
2. Update to version with 3.0 support
3. Test with sample 3.0 specifications
4. Ensure backward compatibility with 2.x

Acceptance Criteria

• AsyncAPI 3.0 specs can be registered
• AsyncAPI 2.x specs continue to work
• Validation errors are meaningful
• Existing tests pass

Effort Estimate

Small - 1-2 days
