Project: Apache Camel
Issue Type: Bug
Components: camel-core
Reporter: Wojciech Durczynski
Priority: Critical

When defining very simple routing with ThreadProcessor I get
ConcurrentModificationException on multicore systems.
Example:

@Override
public void process(Exchange ex) throws Exception {
//sth
}
});
Stack trace:
