Hi Dan - yep, just saw the merges, thanks
> Memory leaks in CXF with spring while using WebClient APIs
> ----------------------------------------------------------
>
> Key: CXF-4795
> URL: https://issues.apache.org/jira/browse/CXF-4795
> Project: CXF
> Issue Type: Bug
> Components: JAX-RS
> Affects Versions: 2.4.2
> Reporter: Ajit Amitav Das
> Priority: Critical
>
> 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
> Already put this
