Christian Schneider resolved ARIES-1270.
----------------------------------------
Resolution: Fixed
Can not be reproduced with 2.0.0-SNAPHOT
> ClasscastException or incompatible type when persistence unit bundle is
> refreshed
> ---------------------------------------------------------------------------------
>
> Key: ARIES-1270
> URL: https://issues.apache.org/jira/browse/ARIES-1270
> Project: Aries
> Issue Type: Bug
> Components: JPA
> Affects Versions: jpa-container-1.0.2, jpa-container-context-1.0.4,
> jpa-container-context-1.0.3
> Reporter: Christian Schneider
> Assignee: Christian Schneider
> Priority: Critical
> Fix For: jpa-2.0.0
>
>
> How to reproduce:
> Follow installation instructions of my tasklist-cdi tutorial
> https://github.com/cschneider/Karaf-Tutorial/tree/master/tasklist-blueprint-cdi
> - After installation the example works
> - refresh net.lr.tasklist.cdi.tasklist-model
> - When accessing http://localhost:8181/tasklist you get the exception below
> - After a restart of karaf it works again
> So the problem seems to be that with a refresh you get a new classloader for
> the model bundle but the persistence unit (EnityManagerFactory) is not
> renewed so it still uses the old classloader.
> I am not yet sure if the problem is in jpa.container or jpa.container.context.
> I will try to recreate this error in an itest for jpa so we can track it
> easily.
