    Description

      I stumbled across this problem whilst having a quick look into ENTESB-4379.

      HawtIO enables users to add new endpoint configurations to camel contexts. The UI should display a helpful select field which provides a list of available camel components. The Jolokia request that populates this data seems broken ever since the camel subsystem upgraded to the revised camel-cdi implementation.

      Given a Jolokia POST to:

      http://localhost:8080/hawtio/jolokia/?maxDepth=7&maxCollectionSize=5000&ignoreErrors=true&canonicalNaming=false

      With Data:

      {"type":"exec","mbean":"org.apache.camel:context=camel-1,type=context,name=\"camel-1\"","operation":"findComponentNames"}

      Results in the error response:

      {"request":{"mbean":"org.apache.camel:context=camel-1,type=context,name=\"camel-1\"","type":"exec","operation":"findComponentNames"},"stacktrace":"java.lang.IllegalStateException: JBAS016071:
Singleton not set for ModuleClassLoader for Module \"org.apache.camel.core:main\" from local module loader @77ec78b9
(finder: local module finder @1a3869f4 (roots: \/tmp\/appserver\/jboss-eap-6.4\/modules,\/tmp\/appserver\/jboss-eap-6.4\/modules\/system\/layers\/fuse,\/tmp\/appserver\/jboss-eap-6.4\/modules\/system\/layers\/soa,\/tmp\/appserver\/jboss-eap-6.4\/modules\/system\/layers\/base)).
This means that you are trying to access a weld deployment with a Thread Context ClassLoader that is not associated with the deployment.

      Not sure whether the fault lies in Weld, camel-cdi or the camel subsystem.
