[jira] [Reopened] (ISIS-1756) JEE Support - IsisContext requires proper lifecycling.

["Andi Huber (JIRA)" <ji...@apache.org>]

Andi Huber reopened ISIS-1756:
------------------------------

Now with the DN-5.1.5-SNAPSHOT class-loading issues seem fixed. But it seems we still do not properly purge all DN state after we shutdown the Isis-context.

I now get exceptions after a deploy/undeply/change-code/deploy cycle:

{code}
Caused by: java.lang.ClassCastException: d.d.A cannot be cast to d.d.A
	at d.d.B.dnReplaceField(A.java)
	at d.d.B.dnReplaceFields(A.java)
	at org.datanucleus.state.StateManagerImpl.replaceFields(StateManagerImpl.java:4286)
{code}

... but only if I had loaded d.d.B before this deployment. That tells me, that there is some state left over.

> The isis-context needs a proper lifecycling, meaning a  deploy/undeploy cycle should properly invalidate any state. (e.g meta model validation is currently not cleared after an undeploy, in my case after calling IsisContext.testReset())
