[jboss-jira] [JBoss JIRA] (WFLY-776) Inject POJO to MBean by using <inject bean="XXX"> in jboss-service.xml does not work in SAR

[Tomek Adamski (JIRA)]

    [ https://issues.jboss.org/browse/WFLY-776?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12929361#comment-12929361 ] 

Tomek Adamski commented on WFLY-776:
------------------------------------

I was able to reproduce the same error that is described. I have found out that it occurrs because mbean and pojo are two different subsystems which are not related to eachother. As a result of that, when mbean subsystem encounters "inject bean" tag it looks for mbean (not pojo) of a given name and if such mbean does not exists it stops deployment of mbean with an error.

I'm wondering how this problem should be solved. There is a possibility of adding such feature but at the first glance, I see the following problems with that:
- it leads to dependence (service naming etc.) between two subsystems
- it can possibly lead to xml syntax change (in order to distinguish between injection of mbean or pojo bean)

Can someone please suggest wheter such extension is desirable?
