it looks like we cannot override CXF's extends if it is in bus-extensions.txt file.
I want to customize cxf's HTTPTransportFactory which defined in bus-extensions.txt. however, it seems I cannot override the original one from CXF. If I create a new bus-extension.txt, and put my customized HTTPTransportFactory there, e.g.
mycxf.jetty.MyJettyHTTPDestinationFactory:org.apache.cxf.transport.http.HTTPTransportFactory:true, CXF will load both my bus-extension.txt and its own bus-extension.txt in ExtensionManager, and will use its HTTPTransportFactory to replace MyJettyHTTPDestinationFactory.
Could you please take a look? thanks.
