Bjørn Ole Myrold updated CAMEL-17844:
-------------------------------------
Description:
Version 3.4.1 introduced fixes in regards to how BeanInfo gets built, this
seems to break beans which are @FunctionalInterfaces.
I believe it was introduced with
https://issues.apache.org/jira/browse/CAMEL-15278
The fix created in the above case only handles super classes, and does not look
at interfaces. A lambda cast to a FunctionalInterface will only provide Object
as super class, and BeanInfo will then not find any methods marked with
@Handler in the interface.
This works in 3.4.0, but not in 3.4.1 or higher
{code:java}
public class TestRoute extends RouteBuilder {
@Override public void configure() throws Exception {
from("direct:testRoute").id("TestRoute")
.setBody().method((Formatter) a -> String.format("%s %s",
a.getName(), a.getOtherName()))
.to("direct:testEndpoint");
}
@FunctionalInterface
public interface Formatter {
@Handler String test(@Body RandomPojo t);
}
} {code}
