Description

I'm doing a POC using clients generated from wsdl2java and Spring Webflux.

When I enable BlockHound to check for any blocking calls, the logger from HTTPTransportFactory blocks: https://github.com/apache/cxf/blob/cxf-3.4.2/rt/transports/http/src/main/java/org/apache/cxf/transport/http/HTTPTransportFactory.java#L71

From debugging, when the logger is initialized, it attempts to load https://github.com/apache/cxf/blob/cxf-3.4.2/rt/transports/http/src/main/java/org/apache/cxf/transport/http/Messages.properties

Loading that file from the containing JAR via ResourceBundle is a blocking operation as far as I can tell.

My expectation is that when I use an async method from the generated client, there should not be any blocking calls made.

I've created a sample project and a failing test that showcases the issue: https://github.com/ciscoo/cxf-blockhound-webflux

I've also attached the stacktrace as well which shows the blocking call.
