--------------------------------------
Hi Sergey,
Regarding the 4th correction suggested by you, I tested following configuration
(as suggested in Section "Configuring HTTP clients in Spring" at
http://cxf.apache.org/docs/jax-rs-client-api.html ), but the client seems
unable to connect to the service.
<jaxrs-client:client id="customerServiceClient"
address="${customer.rest.service.url}"
serviceClass="org.apache.cxf.jaxrs.client.WebClient"
threadSafe="true">
<jaxrs-client:providers>
<ref bean="jsonProvider" />
<bean name="exceptionHandler"
class="com.mycompany.refapp.exception.AppExceptionHandler"/>
</jaxrs-client:providers>
</jaxrs-client:client>
In the Tomcat log, I could see the following. Any pointers on what I am missing?
[2016-06-21 12:37:47,104][WARN ][org.apache.cxf.jaxrs.utils.ResourceUtils]: No
resource methods have been found for resource class

> Key: CXF-6938
> URL: https://issues.apache.org/jira/browse/CXF-6938
> Project: CXF
> Issue Type: Task
> Components: Bus, JAX-RS
> Affects Versions: 3.1.0, 3.1.6
> Environment: Redhat Enterprise Linux (Santiago), OpenJDK 7, Tomcat 7
> Reporter: RANADEEP SHARMA
> Assignee: Sergey Beryozkin
> Priority: Minor
> Fix For: 3.0.10, 3.1.7, 3.2.0
>
>
> We have an application with REST client components for making calls to
> Backend web services. During our routine performance test, JProfiler tool
> shows lots of Bus property entries (with keys named
> "bus.providers.set.<hashCode>") populated while creating instances of
> ClientProviderFactory.
> These Bus property entries seem to stay in heap for the whole duration of the
> 6 hour run. In fact, around 100,000 entries occupying 13 MB of heap.
> In short, GC doesn't seem to happening frequently enough to keep the heap
> usage within limits.
> Is this some sort of a bug or, lack of necessary configuration in CXF?
> Either ways, we need your guidance for trouble-shooting this issue.
