[jboss-jira] [JBoss JIRA] (AS7-2986) ModuleClassLoader can't load HttpClient within a spring loaded bean using RESTEasy

ModuleClassLoader can't load HttpClient within a spring loaded bean using RESTEasy ---------------------------------------------------------------------------------- Key: AS7-2986 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.
