v2.5.4

What's Changed

Draft release notes for the upcoming 2.5.4 release.

What's New

CLI

• Fixed handling for missing or mistyped plugin names. The CLI now reports a clear Plugin not found error instead of falling through to an empty plugin configuration and failing later with a NullPointerException while reading the processor chain.
• Added validation for plugin configurations that do not define a processor chain, so malformed custom plugins fail with a targeted error message.

AsyncAPI JSON Schema to POJO

• Generate POJOs for object schemas declared on selected messages beyond the payload. These are opt-in and off by default, so existing projects keep generating exactly the same classes:
  • generateMessageKeys — message binding keys, e.g. Kafka bindings.kafka.key (#130).
  • generateMessageHeaders — application headers declared on messages or inherited from message traits (#120).
  • generateBindingHeaders — protocol binding header schemas (HTTP/JMS/MQTT).
• Message schemas are now generated in a stable order, and a warning is logged when two schemas would resolve to the same class name instead of one silently overwriting the other.
• Fixed processing of AsyncAPI operation traits containing scalar properties such as title, which previously failed with a ClassCastException (#132).
