-----------------------------------
Summary: camel export fails with MongoTimeoutException for
kamelets using #class: Component beans
Key: CAMEL-24257
URL: https://issues.apache.org/jira/browse/CAMEL-24257
Project: Camel
Issue Type: Bug
Reporter: Claus Ibsen
Fix For: 4.22.0, 4.18.4
camel export fails with MongoTimeoutException / AllNodesFailedException for
kamelets using #class: Component beans (e.g. mongodb-sink, cassandra-sink)
because the real component is instantiated instead of being replaced with
StubComponent.
The root cause is a regression from commit 5d4c6cbf0746 (CAMEL-22667) which
added an outer else branch in KameletMainInjector.acceptComponent(). This
branch also fires when stubPattern is "*" (used by camel export), overriding
accept=false back to true for components not in ACCEPTED_STUB_NAMES, causing
real components like MongoDbComponent / CassandraComponent to be loaded and
attempt connections to non-existent instances.
Fix: remove the outer else branch so that when stubPattern is "*", accept
remains as returned by accept(type) — true for ACCEPTED_STUB_NAMES components,
false for everything else.
