[jira] [Work started] (CAMEL-10584) spring boot auto configuration
mojo: use Class.isAssignableFrom instead of instanceof as the later may
fail at compile time in case of final classes

> Key: CAMEL-10584
> URL: https://issues.apache.org/jira/browse/CAMEL-10584
> Project: Camel
> Issue Type: Improvement
> Components: tooling
> Reporter: Luca Burgazzoli
> Assignee: Luca Burgazzoli
> Fix For: 2.19.0
>
>
> In *AutoConfiguration classes generated by camel-package-plugin, there is a check like
> {code:java}
> if (myInstance instanceof CamelContextAware) {
> ((CamelContextAware) dataformat).setCamelContext(camelContext);
> }
> {code}
> This check may fail at compile time if myInstance is final and it is not an instance of CamelContextAware which make not possible to write final classes.
> We should do something like:
> {code:java}
> if (CamelContextAware.class.isAssignableFrom(MyInstanceType.class)) {
> CamelContextAware context = CamelContextAware.class.cast(myInstance);
> if (context != null) {
> context.setCamelContext(camelContext);
> }
> }
> {code}
