-------------------------------------------------------------------
Sorry, I missed that the problem does not seem to occur with java.util
collections. But it occurs for guava collections (which are pretty popular
imho).
To reproduce use:
{code:xml}
<dependency>
<groupId>com.google.guava</groupId>
<artifactId>guava</artifactId>
<version>21.0</version>
</dependency>
{code}
{code:java}
public class AmbiguousMethodCallExceptionTest extends CamelTestSupport {
public static class AmbiguousMethodCallExceptionRoute extends RouteBuilder {
@Override
public void configure() throws Exception {
from("seda:in").choice().when(simple("${headers.set.size} !=
0")).to("mock:out");
}
}
@Produce(uri = "seda:in")
private ProducerTemplate in;
@EndpointInject(uri = "mock:out")
private MockEndpoint out;
@Override
protected RouteBuilder createRouteBuilder() {
return new AmbiguousMethodCallExceptionRoute();
}
@Test
public void ambiguousMethodCallException() throws Exception {
out.expectedMessageCount(1);
ExchangeBuilder exchangeBuilder = new
ExchangeBuilder(context).withHeader("set", ImmutableSet.of("a"));
in.send(exchangeBuilder.build());
out.assertIsSatisfied();
}
}{code}
{code:java}
public class MethodNotFoundExceptionTest extends CamelTestSupport {
public static class MethodNotFoundExceptionRoute extends RouteBuilder {
@Override
public void configure() throws Exception {
from("seda:in").choice().when(simple("${headers.set.isEmpty()} !=
true")).to("mock:out");
}
}
@Produce(uri = "seda:in")
private ProducerTemplate in;
@EndpointInject(uri = "mock:out")
private MockEndpoint out;
@Override
protected RouteBuilder createRouteBuilder() {
return new MethodNotFoundExceptionRoute();
}
@Test
public void methodNotFoundExceptionException() throws Exception {
out.expectedMessageCount(1);
ExchangeBuilder exchangeBuilder = new
ExchangeBuilder(context).withHeader("set", ImmutableSet.of("a"));
