[jira] [Commented] (AMQ-3696) Slave broker cannot be stopped in a
JDBC Master/Slave configuration within OSGi
[ https://issues.apache.org/jira/browse/AMQ-3696?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13417112#comment-13417112 ]
Dejan Bosanac commented on AMQ-3696:
------------------------------------
svn revision 1362950 changes the behavior of start() method, in that it will not block for slave scenario. This change should fix the root of this problem.
One side-effect is that in standalone scenario, web console is started for slaves as well. I need to fix web console to show meaningful display for slaves as well.

> A Blueprint container cannot be stopped while it is in the state "Creating" because both operations are synchronized in BlueprintContainerImpl.
> The impact is that a slave broker cannot be stopped. Fortunately, before the broker itself is stopped, first the OSGi services are unregistered, which calls the configured OSGi unregistration listeners.
> This patch provides a class which is a OSGi service unregistration listener, to allow to stop the database locker, while it is blocked in the "Creating" state.
