      Description

      Problem - We are facing a very weird memory issue while using spring (3.0.5.RELEASE) with Apache-CXF(2.4.2). We are trying to make a REST(GET) call using Apache CXF WebClient.get().Each outbound call URL is getting configured as a bean in the Spring Container.

      Description -
      1.Placeholder in Spring where the URL is getting configured as a Bean
      Class Name - AbstractBeanFactory
      private final Set<String> alreadyCreated = Collections.synchronizedSet(new HashSet<String>());

      2.Reason

      During the WebClient.get call CXF prepares conduit to channel the message to destination. Since it is a HTTP call HTTPTransportFactory is used to create HTTP Conduit for the endpoint.
      This is done by HTTPTransportFactory.getConduit method.
      HTTPTransportFactory.getConduit invokes HTTPTransportFactory.configure(Object bean, String name, String extraName)

      protected void configure(Object bean, String name, String extraName) {
      Configurer configurer = bus.getExtension(Configurer.class);
      if (null != configurer) {
      configurer.configureBean(name, bean);
      if (extraName != null)

      { configurer.configureBean(extraName, bean); }


      }
      }

      name parameter value is -

      {http://<ip>:<port>/<application-context>/user/96BEEBE3119B4B809F35CFFAF5EA9803/detail}

      WebClient.http-conduit

      extraName parameter value is - http://<ip>:<port>/<application-context>/user/96BEEBE3119B4B809F35CFFAF5EA9803/detail

      Since CXF by default uses SpringBus,the configurer class returned for bus.getExtension(Configurer.class) call is org.apache.cxf.configuration.spring.ConfigurerImpl .
      This class ends up configuring both the above mentioned URL as bean in Spring.

      This bean names are keep on adding to a Set instance alreadyCreated which never get garbage collected, and keep increasing the memory footprint and finally causing OutOfMemory issue.

      My application is growing with huge memory foot print as the number of outbound calls increases, we are forced to bounce back the server in frequent intervals
