Description

The 3.6.0 version brakes our route tests.

In the code below we have two xpath expressions. Debugging shows, that the second one in split uses Long.class as return type for evaluation which is wrong and split silently fails (No split done).

if you remove 

 .setProperty("BOOK_COUNT", xpath( "//Books/@count", Long.class))

test will pass.

Verified by test based on Camel Quarkus :: Examples :: Rest Json

<camel-quarkus.version>1.3.0</camel-quarkus.version>
<quarkus.version>1.9.0.Final</quarkus.version>

package org.acme.rest.json;
import org.apache.camel.builder.RouteBuilder;
import java.util.concurrent.atomic.AtomicInteger;

public class Routes extends RouteBuilder {

    private AtomicInteger splitCount = new AtomicInteger();

    @Override
    public void configure() throws Exception {
        from("platform-http:/xpathtest?httpMethodRestrict=POST")
                .process(exchange -> splitCount.set(0))
                .setProperty("BOOK_COUNT", xpath( "//Books/@count", Long.class))
                .split(xpath("//Books/Book"))
                    .process(exchange -> splitCount.getAndIncrement())
                .end()
                .setBody(exchange -> splitCount.get())
                .marshal().json();

    }
}
