---------------------------------

             Summary: Class cast Exception when undeploying application with @PostConstruct LifeCycle
                 Key: TOMEE-4032
                 URL: https://issues.apache.org/jira/browse/TOMEE-4032
             Project: TomEE
          Issue Type: Bug
          Components: TomEE Core Server
    Affects Versions: 9.0.0-M8, 9.0.0-M9
            Reporter: Rob Leland
         Attachments: Stack-9.0.0-M8.log, Stack-9.0.0-M9-Sept-02-2022-GitHash-68be80e.log

A Class cast Exception is occurring , see attachment ,when stopping the container. The app is using  using @PostConstruct & @EJB Annotation.

 

This does not occur with GlassFish, 6.2.5.

But does for:
ENV:

TomEE Plus & MicroProfile TC v10.0.21/TCE: 9.0.0-M8
With OpenJDK 11 & 17 Under Ubuntu 22.04.

( I also built a Nightly from 9/2/2022 GitHash: [68be80e|https://github.com/free2create/tomee/commit/68be80e60291468a1c196b503837921e59e64a87])  using java 17 and the same error Occurs, I have also attached stack trace for that also. The Line # are the same.


The Generated WAR WEB-INF/lib folder only has Derby Jars nothing else.

The Repo with this app is at:
[https://github.com/free2create/pro-jakarta-persistence-jakarta-ee10]

It uses maven to build and after building you would want to deploy:

examples/Chapter3/03-slsbLifecycleExample/servlet/target/ WAR file.

 

To reproduce you just need to deploy the app, and shutdown tomcat, no need to exercise the application.

But if you did want to test the app this is the URL:

[http://localhost:8080/ch3-03-slsb-servlet-1.0.0/LoggerServlet]
