Thomas,
the wrong XWikiContext only occurs, when I use a ScriptService
Implementation to inject it.
If I start the Job from inside a Macro Implementation everything is fine.
Regards, Stefan.

There is something very weird in your stack trace, you clearly have a
XWikiContext in the ExecutionContext as otherwise you would get a
nullpointer in your own code before AbstractDataMigrationManager so
what you have really does not make any sense to me. Without debugging
I don't have much idea. Also the stack trace you have clearly indicate
that this thread has been executed with in the XWikiContext a wiki
that was not initialized.
Does mycon.getDatabase() contains what you expect ? On Fri, Nov 21, 2014 at 8:42 AM, Stefan

Again as I told you the ExecutionContext is properly initialized but
the XWikiContext is something else, the Provider among other things
create and set a XWikiContext when there is none. Now what is wrong is
that you end up in AbstractDataMigrationManager in your thread since
its supposed to be called only the first time a request is done.
When do you start your job exactly ? Are you sure the database is
ready when you do (it's not before the first access to the wi trough
the browser) ? You can listen to
org.xwiki.bridge.event.ApplicationReadyEvent to be notified when it's
ok to use the database.
The job is started from a macro class. So the wiki itself
should be
fully
initialized.
