[jboss-jira] [JBoss JIRA] (WFLY-13185) Rest-client can't be used without opentracing subsystem present in config

[Matěj Novotný (Jira)]

    [ https://issues.redhat.com/browse/WFLY-13185?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13990085#comment-13990085 ] 

Matěj Novotný commented on WFLY-13185:
--------------------------------------

[~rsearls], [~jdenise] so, this is some form of class loading problem, not a Weld issue.
If you enable Weld DEBUG logging in that server (edit {{logging.properties, set DEBUG levels and add {{logger.org.jboss.weld.level=DEBUG}}), you will see something like:
{code}
15:38:43,138 DEBUG [org.jboss.weld.deployer] (Weld Thread Pool -- 1) Unable to load annotation org.eclipse.microprofile.rest.client.inject.RegisterRestClient
15:38:43,141 DEBUG [org.jboss.weld.deployer] (Weld Thread Pool -- 4) Unable to load annotation org.eclipse.microprofile.rest.client.inject.RestClient
{code}

What this means is that Weld cannot load those annotations from CL, whereas in standard WFLY this works. So there is probably some difference in how the MP RE API is made available.
