[jira] [Commented] (CAMEL-11235) Simple Language: Set#size fails
with AmbiguousMethodCallException when using guava collections
[ https://issues.apache.org/jira/browse/CAMEL-11235?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16001183#comment-16001183 ]
Pascal Schumacher commented on CAMEL-11235:
-------------------------------------------
This issue can also be replicated with java.util classes, e.g. using LinkedHashSet:
{code}
package test;
import java.util.LinkedHashSet;
import java.util.Set;
import org.apache.camel.EndpointInject;
import org.apache.camel.Produce;
import org.apache.camel.ProducerTemplate;
import org.apache.camel.builder.ExchangeBuilder;
import org.apache.camel.builder.RouteBuilder;
import org.apache.camel.component.mock.MockEndpoint;
import org.apache.camel.test.junit4.CamelTestSupport;
import org.junit.Test;
public class AmbiguousMethodCallExceptionTest extends CamelTestSupport {
public static class AmbiguousMethodCallExceptionRoute extends RouteBuilder {
@Override
public void configure() throws Exception {
from("seda:in").choice().when(simple("${headers.set.size} != 0")).to("mock:out");
}
}
@Produce(uri = "seda:in")
private ProducerTemplate in;
@EndpointInject(uri = "mock:out")
private MockEndpoint out;
@Override
protected RouteBuilder createRouteBuilder() {
return new AmbiguousMethodCallExceptionRoute();
}
@Test
public void ambiguousMethodCallException() throws Exception {
out.expectedMessageCount(1);
Set<String> set = new LinkedHashSet<>();
set.add("a");
ExchangeBuilder exchangeBuilder = new ExchangeBuilder(context).withHeader("set", set);
in.send(exchangeBuilder.build());
out.assertIsSatisfied();
}
}
{code}
