------------------------------------
Summary: Cannot cast ResumeActionAwareAdapter to
KenisisResumeAdapter
Key: CAMEL-20840
URL: https://issues.apache.org/jira/browse/CAMEL-20840
Project: Camel
Issue Type: Bug
Components: camel-aws2-kinesis
Affects Versions: 4.6.0
Reporter: Mark Wimpory
When setting up the KinesisConsumer to use the KinesisResumeAdapter this error
is thrown.
java.lang.ClassCastException: Cannot cast
org.apache.camel.support.resume.ResumeActionAwareAdapter to
org.apache.camel.component.aws2.kinesis.consumer.KinesisResumeAdapter
at java.base/java.lang.Class.cast(Class.java:3889)
at org.apache.camel.resume.ResumeStrategy.getAdapter(ResumeStrategy.java:62)
I have isolated this to the following problem.
The KinesisConsumer DOES NOT override the default method in ResumeAware that
specified the adapter name:
default String adapterFactoryService() {
return "adapter-factory";
}
This leads to a classpath clash with the camel-support jar that is also use the
name adapter-factory. In this case the factory service when called for Kinesis
creates the wrong type of adapter as above.
Other Resumable consumers have renamed their factory files for instance the
file consumer uses file-adapter-factory.
I have created a work around locally (that I dont like) by creating in my own
classpath a duplicate of the adapter factory. This is loaded in preference to
the jar resources but is not a perm fix.
The fix required is to: * Change the Kinesis2Consumer to override the method
above and return its own factory name such as kinesis-adapter-factory
* Change the build so that the adapter-factory file is replaced with
kinesis-adapter-factory
