---------------------------------------
Summary: weaveAddLast throwing UnsupportedOperation when route
have a ChoiceDefinition
Key: CAMEL-8798
URL: https://issues.apache.org/jira/browse/CAMEL-8798
Project: Camel
Issue Type: Bug
Components: camel-core
Affects Versions: 2.15.2, 2.15.1, 2.15.0, 2.14.2
Environment: JDK 7.0 64bits
Reporter: Terral Guillaume
I'm currently upgrading from Camel 2.14.1 to 2.15.2, after the upgrade some of
my test are failing.
My route is:
{code}from("file:input?idempotent=true&moveFailed=.error").routeId("MyRoute")
.choice()
.when(body().isEqualTo("body1"))
.log("body1")
.otherwise()
.log("notBody1")
.end()
{code}
My test contains :
{code}camelContext.getRouteDefinition("MyRoute").adviceWith(camelContext, new
AdviceWithRouteBuilder() {
@Override
public void configure() {
weaveAddLast().to(mockOutput);
}
});
{code}
The weaveAddLast is failing with the following stackTrace:
{code}
java.lang.UnsupportedOperationException
at java.util.AbstractList.add(AbstractList.java:148)
at
org.apache.camel.builder.AdviceWithTasks$4.task(AdviceWithTasks.java:298)
at
org.apache.camel.model.RouteDefinition.adviceWith(RouteDefinition.java:270)
{code}
After some debug I found that when my route and with a Choice I cannot
weaveAddLast the route.
When the AdviceWithTasks task method try to add the outputs (here) the
implementation of the list return by the ChoiceDefinition class does not
implements the method add(int,Object) then we have the UnsupportedOperation
The difference between 2.14.1 and 2.15.2 is that in the AdviceWithTasks the
outputs list where the weaveAddLast try to find the last Processor to add the
outputs is not a list returned by ChoiceDefinition but it's a list with the
Logs processor.
This difference is there because now in 2.15.2 the method that is going through
the route to retrieve the outputs nodes have a maximum depth which is computed
here
When my route have finish with a ChoiceDefinition the maximum depth computed is
only 1 then I cannot have my logs in outputs an the weaveAddLast have in his
list only the ChoiceDefinition.
