Camel error using InterceptFrom and Intercept strategy at the same time
Issue
- Testing a route including camel's custom InterceptStrategy, http://camel.apache.org/intercept.html, got a StackOverFlowError as below,
org.apache.camel.CamelExecutionException: Exception occurred during execution on the exchange: Exchange[Message: Test]
at org.apache.camel.util.ObjectHelper.wrapCamelExecutionException(ObjectHelper.java:1379)

- Below is the code that we tested with,
protected RouteBuilder createRouteBuilder() throws Exception {
return new RouteBuilder() {
@Override
public void configure() throws Exception {
// add a dummy strategy
// removing this line the test works
context.addInterceptStrategy(new DummyStrategy());
// intercet from
interceptFrom("direct:start").log("Intercepted");
from("direct:start").to("mock:result");
}
};
}
class DummyStrategy implements InterceptStrategy {
@Override
public Processor wrapProcessorInInterceptors(CamelContext context, ProcessorDefinition<?> definition, Processor target, Processor nextTarget)
throws Exception {
return target;
}
}
- The stack shows me
