             Summary: Since Spring 5.1.5 Release CXFServlet application listener dissapears by context refresh
                 Key: CXF-8130
                 URL: https://issues.apache.org/jira/browse/CXF-8130
             Project: CXF
          Issue Type: Bug
          Components: Transports
    Affects Versions: 3.3.3, 3.3.2
            Reporter: Roman Platonov


Hi,

I have following problem after the changes in Spring Framework [commit there|[https://github.com/spring-projects/spring-framework/blob/9689a59ab1b8432d8eba688247fc5cb86e602871/spring-context/src/main/java/org/springframework/context/support/AbstractApplicationContext.java#L606]]

So, at the start of the application startup there is a call of {{prepareRefresh()}}, so it works like that:

 
{code:java}
this.earlyApplicationListeners = new LinkedHashSet<>(this.applicationListeners);
{code}
 

{{}}

and this collection is empty.

Then is CXFServlet I have addition of listener - [Cxf link| https://github.com/apache/cxf/blob/ec4423437bd7d6b63e3464761394cfafb50cacfa/rt/transports/http/src/main/java/org/apache/cxf/transport/servlet/CXFServlet.java#L90]

 

Then it's needed to refresh the Application Context, so it provokes the {{refresh()}} at AbstractApplicationContext, then goes to {{prepareRefresh}} and then checks

{{}}
{code:java}
this.earlyApplicationListeners == null,{code}
but it's an empty LinkedHashSet, not null, so then it comes to
{{}}
{code:java}
this.applicationListeners.clear(); {code}
{{}}

and it removes the listener from CXFServlet, so there is no event coming to CXFServlet.

Is there any solution? Maybe it's better to change the logic of addition the listener to context?

 

I have also add the comment to spring framework issue ([Issue|[https://github.com/spring-projects/spring-framework/issues/22325]])

 

Thank you!
