JaxRs: reuse of WebTarget can cause OOM

[Hartmut Lang]

Hi,

my question is how i can reuse (or not) the WebTarget of a JaxRs Client
with CXF 3.0.2.

My scenario is roughly like this:

Init:
Client client = ClientBuilder.newBuilder().
                register(JacksonJsonProvider.class).
                build();
WebTarget target = client.target(baseUrl).path("lights/{lightNum}/{state}");


Then i issue several (thousands) requests like this:

Invocation.Builder builder = target.
                resolveTemplate("lightNum", lightNum).
                resolveTemplate("state", state).
                request();
Response response = builder.put(null);
response.close();

What i see is, that for every request a new WebClient-Object is created and
added to
ClientImpl.baseClients-HashMap.
And finally i can run into OOM-issues.

My question:
- is it ok to reuse the WebTarget for several requests?
- if i close the client and create a new one, this solves this issue. Is
this the intended live-cycle of Client/WebTarget?

Thanks,
Hartmut
