Subject [jira] [Commented] (CXF-7409) ServiceConstructionException when adding JAX-RS application ruins existing applications
Date Wed, 09 Aug 2017 15:09:00 GMT

    [ https://issues.apache.org/jira/browse/CXF-7409?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16120053#comment-16120053
] 

Carlos Sierra commented on CXF-7409:
------------------------------------

In our case this address is coming from a property on a OSGi service reference. 

We are avoiding it at the moment using a custom destination Factory to detect the conflict
before it gets to destroy the server. 
To be honest I did not think having several applications per servlet would be a problem. Would
you suggest we spawn a servlet for each of the applications? If you think CXF does not support
other way I will refactor and make sure there is only one application per servlet (if no other
considerations apply)

I will try and find some time to create a test for you. I need to get acquainted with your
tree. But with you comments I guess you encouraged me to change our implementation and completely
work around this problem from the root.

that invocation is there to prevent leaks. Also, invocations to server.destroy() in other
moments don't affect other existing applications in the bus.
