      We have a simple camel-cxf route:

      from("cxf:bean:cxfServerBean")
                .setHeader(Exchange.HTTP_METHOD, constant(HttpPost.METHOD_NAME))
                .setHeader(Exchange.CONTENT_TYPE, constant("application/xml"))
                .removeHeader(Exchange.HTTP_PATH)
                .to("http://localhost:8081/hello?bridgeEndpoint=true");

      However, it throws a ClassCastException:

      java.lang.ClassCastException: class java.util.ArrayList cannot be cast to class java.util.Map (java.util.ArrayList and java.util.Map are in module java.base of loader 'bootstrap')
	at org.apache.camel.component.cxf.jaxws.DefaultCxfBinding.extractInvocationContextFromCamel(DefaultCxfBinding.java:598)
	at org.apache.camel.component.cxf.jaxws.DefaultCxfBinding.populateCxfHeaderFromCamelExchangeBeforeCheckError(DefaultCxfBinding.java:396)
	at org.apache.camel.component.cxf.jaxws.CxfConsumer$CxfConsumerInvoker.setResponseBack(CxfConsumer.java:321)

	at org.apache.camel.component.cxf.jaxws.CxfConsumer$CxfConsumerInvoker.invoke(CxfConsumer.java:164)
......

      The "ResponseContext" header was populated in the camel exchange IN message after invoking against the other camel endpoint "http://localhost:8081/hello?bridgeEndpoint=true". The method "extractInvocationContextFromCamel" of the DefaultCxfBinding class was also called. Because the "ResponseContext" header was initialised as an ArrayList type, therefore, the exception was thrown at the line #598 in the DefaultCxfBinding.java class:
