                 URL: https://issues.jboss.org/browse/AS7-2986
             Project: Application Server 7
          Issue Type: Bug
          Components: Class Loading
    Affects Versions: 7.1.0.Beta1b
            Reporter: Michael Steffens
            Assignee: David Lloyd


Can't instantiate a HttpClient within a spring loaded bean using RESTEasy.

Depending on whether resteasy-jaxrs included in war archive (scope "compile") or not included (scope "provided"), the ModuleClassLoader is trapped by either a duplicate class object, or none at all.

See http://community.jboss.org/message/640810 for further details and example code.

Tried following workarounds, but failed:

If you change the code not to instantiate HttpClient explicitly, as in

  private ClientExecutor createClientExecutor()
  {
    ClientExecutor clientExecutor = new ApacheHttpClient4Executor();
    return clientExecutor;
  }

the code runs fine. But then you can't attach Credentials (not acceptable). Or you need to query the ClientExecutor's HttpClient afterwards, and cast the result to DefautHttpClient -> Class loader issue is back again.
